Making Tofu from Roasted Soybeans: A Comprehensive Guide

You know, I’ve always been fascinated by the alchemy of turning simple soybeans into silky, delicious tofu. It’s one of those processes that seems magical until you dive into the science behind it. I remember the first time I tried making tofu at home—it was a disaster. The curds didn’t set, the texture was all wrong, and I ended up with something more akin to soybean soup than tofu. But I was hooked. There’s something about the challenge of mastering a craft, especially one as ancient and culturally significant as tofu-making.

This guide is the culmination of years of experimentation, research, and a fair bit of trial and error. We’re going to explore making tofu from roasted soybeans, which adds a nutty depth of flavor that’s often missing in store-bought versions. Whether you’re a home cook looking to expand your skills or a professional chef aiming to bring house-made tofu to your menu, this guide will walk you through the process step by step.

By the end of this article, you’ll understand the science behind tofu coagulation, the role of roasting in flavor development, and how to achieve the perfect texture. You’ll also learn how to troubleshoot common issues, because let’s face it—things don’t always go as planned in the kitchen. So, let’s roll up our sleeves and get started on this tofu-making journey.

Understanding the Basics of Tofu Making

Before we dive into the process, it’s important to understand what tofu actually is. At its core, tofu is soybean curd, formed by coagulating soy milk and then pressing the resulting curds into blocks. The process is similar to making cheese from dairy milk, which is why tofu is often referred to as “soy cheese.” The key to successful tofu-making lies in understanding the role of each ingredient and step in the process.

First, there are the soybeans themselves. Soybeans are packed with protein and fat, which are essential for creating the structure of tofu. When soybeans are soaked and blended with water, they release these proteins and fats into the liquid, creating soy milk. The quality of your soybeans will directly impact the quality of your tofu, so it’s worth seeking out high-quality, organic soybeans if possible.

Next, there’s the coagulant. This is what causes the proteins in the soy milk to bind together, forming curds. Traditional coagulants include gypsum (calcium sulfate), nigari (magnesium chloride), and even lemon juice or vinegar. Each coagulant imparts a slightly different texture and flavor to the tofu, so experimenting with different types can be part of the fun.

Finally, there’s the process of pressing the curds. Once the soy milk has coagulated, the curds need to be separated from the whey (the liquid left behind) and pressed into a block. The amount of pressure applied and the duration of pressing will determine the firmness of your tofu. More pressure and longer pressing times yield firmer tofu, while less pressure and shorter times result in a softer, more delicate product.

The Role of Roasting

Roasting the soybeans before making tofu is a technique that adds a layer of complexity to the flavor profile. When soybeans are roasted, the Maillard reaction occurs, which is the same process that gives browned meat its rich, savory flavor and toasted bread its golden crust. This reaction creates new flavor compounds that enhance the nutty, slightly sweet taste of the soybeans.

Roasting also affects the texture of the final tofu. The heat from roasting can denature some of the proteins in the soybeans, which may lead to a slightly different curd formation during coagulation. In my experience, tofu made from roasted soybeans tends to have a slightly denser, more cohesive texture, which can be particularly desirable for grilling or frying.

Selecting and Preparing Your Soybeans

Not all soybeans are created equal, and the type you choose can significantly impact your tofu-making process. For this guide, I recommend starting with organic, non-GMO soybeans. These are widely available online or in health food stores. Look for soybeans that are uniform in size and color, as this indicates consistency in moisture content and maturity.

You’ll also want to decide whether to use whole soybeans or split soybeans. Whole soybeans are exactly what they sound like—the entire bean with the hull intact. Split soybeans, on the other hand, have been mechanically split in half, which can make them easier to work with. For tofu-making, either type will work, but I’ve found that whole soybeans tend to produce a slightly creamier soy milk, which can be beneficial for achieving a smooth tofu texture.

Before you begin, you’ll need to measure out your soybeans. A good rule of thumb is to use about 1 cup of dried soybeans for every 4 cups of water. This ratio will give you a good balance of soy milk concentration, which is key for proper coagulation. If you use too few soybeans, your soy milk will be too dilute, and your tofu may not set properly. Conversely, using too many soybeans can result in overly thick soy milk, which can lead to dense, heavy tofu.

Soaking the Soybeans

Once you’ve selected your soybeans, the next step is to soak them. Soaking serves two main purposes: it rehydrates the dried soybeans, making them easier to blend, and it initiates the germination process, which can enhance the nutritional profile of the soybeans. To soak your soybeans, simply place them in a large bowl and cover them with plenty of water. The soybeans will absorb a significant amount of water, so make sure to use at least three times the volume of water as soybeans.

Let the soybeans soak for at least 8 hours, or overnight. You’ll know they’re ready when they’ve roughly doubled in size and can be easily split in half with your fingernail. If you’re in a hurry, you can use hot water to speed up the soaking process, but be aware that this may slightly alter the flavor of the final tofu. I’ve found that a slow, cold soak yields the best results in terms of both texture and taste.

After soaking, drain and rinse the soybeans thoroughly. You’ll notice that the soybeans have softened significantly, and the hulls may have loosened. Some tofu-makers prefer to remove the hulls at this stage, as they can contribute a slightly bitter flavor to the tofu. To remove the hulls, simply rub the soaked soybeans between your palms under running water. The hulls will float away, leaving you with just the cotyledons (the meat of the soybean).

Roasting the Soybeans

Roasting is where the magic starts to happen. This step is optional, but I highly recommend it for the added depth of flavor it brings to the tofu. To roast your soybeans, preheat your oven to 350°F (175°C). Spread the soaked and drained soybeans out on a baking sheet in a single layer. You want to make sure they’re not too crowded, as this can lead to uneven roasting.

Place the baking sheet in the oven and roast the soybeans for about 20-30 minutes, stirring occasionally to ensure even browning. You’re looking for a light golden color—think toasted almonds rather than darkly browned coffee beans. The soybeans should smell nutty and aromatic, but not burnt. If you start to smell any acrid or bitter notes, you’ve likely over-roasted them, which can impart an unpleasant flavor to your tofu.

Once the soybeans are roasted to your liking, remove them from the oven and let them cool slightly. They should be warm but not too hot to handle. At this point, you can proceed with making the soy milk, or you can let the roasted soybeans cool completely and store them in the refrigerator for up to a day before continuing. I’ve found that letting the soybeans rest after roasting can actually enhance their flavor, as some of the compounds created during the Maillard reaction continue to develop over time.

Making Soy Milk from Roasted Soybeans

Now that your soybeans are roasted and ready, it’s time to turn them into soy milk. This is the foundation of your tofu, so it’s important to get it right. The process involves blending the soybeans with water and then straining out the pulp, leaving you with smooth, creamy soy milk.

Start by placing your roasted soybeans in a blender. Add about 4 cups of fresh water for every cup of dried soybeans you started with. The water should be hot but not boiling—around 180°F (82°C) is ideal. Hot water helps to extract more of the soybeans’ proteins and fats, resulting in a richer soy milk. If you don’t have a way to heat the water to this temperature, you can use cold water, but you may need to blend for a bit longer to achieve the same results.

Blend the soybeans and water on high speed for about 2-3 minutes, or until the mixture is completely smooth. You may need to stop and scrape down the sides of the blender a few times to ensure everything is evenly blended. The mixture should look like a thin, slightly grainy puree. If it’s too thick, you can add a bit more water, but be cautious—adding too much water will dilute the soy milk, which can lead to weak tofu curds.

Straining the Soy Milk

Once your soybean mixture is fully blended, it’s time to strain out the pulp. This step is crucial for achieving smooth, creamy soy milk. The traditional tool for this job is a soy milk bag, which is a fine-mesh cloth designed specifically for straining soy milk. If you don’t have a soy milk bag, you can use a clean kitchen towel, a piece of cheesecloth, or even a fine-mesh strainer lined with a coffee filter.

Set up your straining apparatus over a large bowl or pot to catch the soy milk. Pour the blended soybean mixture into the bag or cloth and begin to squeeze and press the liquid out. This can be a bit messy, so I recommend doing it over the sink or on a surface that’s easy to clean. The pulp left behind is called okara, and it’s actually a valuable byproduct in its own right. Okara is high in fiber and protein and can be used in a variety of recipes, from baked goods to veggie burgers.

Continue straining until you’ve extracted as much liquid as possible from the pulp. You should be left with a smooth, slightly frothy liquid that’s the color of creamy coffee. This is your fresh soy milk, and it’s ready to be turned into tofu. At this point, you can taste the soy milk to get a sense of its flavor. It should be slightly sweet, with a nutty undertone from the roasted soybeans. If it tastes bitter or overly beany, it may indicate that the soybeans were over-roasted or that the soy milk was extracted too aggressively, resulting in some of the bitter compounds from the pulp making their way into the milk.

Coagulating the Soy Milk

Coagulation is the process by which the proteins in the soy milk bind together to form curds, which will eventually become your tofu. This is where the science of tofu-making really comes into play. The coagulant you choose will interact with the proteins in the soy milk, causing them to denature and bind together. The type of coagulant, its concentration, and the temperature of the soy milk all play a role in determining the texture and flavor of your final tofu.

For this guide, I recommend using gypsum (calcium sulfate) as your coagulant. Gypsum is a traditional coagulant that produces tofu with a smooth, slightly firm texture and a clean, neutral flavor. It’s also a good source of calcium, which is a nice bonus. You can find food-grade gypsum online or in some specialty food stores. If you can’t find gypsum, nigari (magnesium chloride) is another excellent option, though it can produce a slightly softer tofu with a more pronounced mineral flavor.

To prepare your coagulant solution, dissolve about 1 teaspoon of gypsum in 1/4 cup of warm water. Stir well to ensure the gypsum is fully dissolved. The water should be clear, with no visible particles of gypsum remaining. If you’re using nigari, follow the same process, but you may need to adjust the amount slightly, as it can be more potent than gypsum.

Heating the Soy Milk

Before adding the coagulant, you’ll need to heat the soy milk to the proper temperature. This step is crucial, as the temperature of the soy milk will affect how the proteins interact with the coagulant. If the soy milk is too cold, the coagulation process may be slow or incomplete. If it’s too hot, the proteins may denature too quickly, resulting in a grainy or uneven texture.

Transfer your fresh soy milk to a pot and place it over medium heat. You’ll want to bring the soy milk to a temperature of about 175°F (80°C). Use a thermometer to monitor the temperature closely, as soy milk can scorch easily if heated too quickly. Stir the soy milk gently as it heats to prevent a skin from forming on the surface and to ensure even heating.

As the soy milk heats, you may notice a slight froth forming on the surface. This is normal and is simply a result of the proteins and fats in the soy milk reacting to the heat. You can skim this froth off if you like, but it’s not necessary—it won’t affect the final tofu. Once the soy milk reaches the target temperature, remove it from the heat and let it cool slightly, to about 160°F (71°C). This is the ideal temperature for adding the coagulant.

Adding the Coagulant

Now comes the moment of truth—adding the coagulant to the soy milk. This is where the transformation from liquid to curd begins, and it’s always a bit thrilling to watch. The key here is to add the coagulant slowly and gently, to ensure even distribution and proper curd formation.

Start by stirring the soy milk gently in a circular motion. You want to create a slight vortex in the center of the pot, which will help to distribute the coagulant evenly. Slowly pour the coagulant solution into the vortex, continuing to stir gently as you do so. The goal is to incorporate the coagulant without breaking up the forming curds, so be as gentle as possible.

Once all the coagulant has been added, stop stirring and let the soy milk sit undisturbed. This is where the magic happens. Over the next few minutes, you’ll start to see the soy milk separating into curds and whey. The curds will begin to form a soft, custard-like mass, while the whey will be a clear, yellowish liquid. This process can take anywhere from 5 to 15 minutes, depending on the temperature of the soy milk, the type of coagulant used, and the concentration of proteins in the soy milk.

Monitoring the Coagulation Process

As the curds form, you’ll want to keep a close eye on the process. The ideal coagulation results in a single, cohesive mass of curds that can be easily transferred to a mold for pressing. If the curds are too soft or fragmented, it may indicate that the soy milk was too dilute, the coagulant was insufficient, or the temperature was off. Conversely, if the curds are too firm or rubbery, it may suggest that too much coagulant was used or that the soy milk was too hot.

If, after 15 minutes, the soy milk hasn’t fully coagulated, you can try adding a bit more coagulant. Dissolve another 1/2 teaspoon of gypsum in a tablespoon of warm water and gently stir it into the soy milk. Wait another 5-10 minutes to see if the additional coagulant does the trick. If the soy milk still hasn’t coagulated, it may be too dilute to form proper curds. In this case, you can try heating the mixture gently to evaporate some of the liquid, which may concentrate the proteins enough to allow coagulation.

Once the soy milk has fully coagulated, you should be able to see a clear separation between the curds and the whey. The curds will be a soft, custard-like mass, while the whey will be a clear, yellowish liquid. At this point, you’re ready to transfer the curds to a mold for pressing. But first, let’s talk about the tools you’ll need for this next step.

Tools for Pressing Tofu

Pressing the tofu is a crucial step in achieving the right texture. The amount of pressure applied and the duration of pressing will determine the firmness of your tofu. For this guide, I’ll walk you through using a traditional tofu press, but I’ll also share some alternative methods in case you don’t have a press on hand.

A traditional tofu press consists of a perforated mold and a pressing mechanism. The mold is typically a square or rectangular box with small holes in the bottom to allow the whey to drain out. The pressing mechanism can be as simple as a weight placed on top of the curds or as elaborate as a lever system that applies even pressure. If you’re serious about making tofu regularly, investing in a quality tofu press can be worthwhile, as it will give you the most consistent results.

If you don’t have a tofu press, don’t worry—there are plenty of household items you can use to achieve similar results. A colander lined with cheesecloth can work as a makeshift mold, and you can use a heavy pot or a stack of books as a weight to press the curds. The key is to ensure that the whey can drain freely from the curds and that the pressure applied is even and consistent.

Preparing Your Press

Before transferring the curds to the press, you’ll want to make sure everything is set up properly. If you’re using a traditional tofu press, line the mold with a piece of cheesecloth or a clean kitchen towel. This will help to keep the curds contained and make it easier to remove the tofu once it’s pressed. If you’re using a colander, line it with several layers of cheesecloth to prevent the curds from slipping through the holes.

Place the lined mold or colander over a bowl or in the sink to catch the whey as it drains. Make sure the setup is stable and that the mold or colander is level, as this will ensure even pressing and a uniform texture in the final tofu. If you’re using a weight to press the tofu, have it ready nearby so you can transfer the curds quickly and begin pressing immediately.

Once your press is prepared, it’s time to transfer the curds. Gently scoop the coagulated curds from the pot and place them into the lined mold or colander. Be careful not to break up the curds too much, as this can lead to a crumbly texture in the final tofu. If the curds are particularly soft, you can use a slotted spoon or a fine-mesh strainer to transfer them, which will help to leave some of the whey behind.

Pressing the Tofu

With the curds safely transferred to the mold, it’s time to begin pressing. The goal here is to remove as much whey as possible from the curds, which will result in a firmer, more cohesive tofu. The amount of time you press the tofu will depend on the level of firmness you’re aiming for. For a soft, silken tofu, you may only need to press for 10-15 minutes. For a firmer tofu, you’ll want to press for at least 30 minutes, and possibly up to an hour.

If you’re using a traditional tofu press, follow the manufacturer’s instructions for applying pressure. Typically, this involves placing a lid or follower board on top of the curds and then using a lever or weight to apply pressure. Start with a gentle pressure and gradually increase it as the whey drains out. If you’re using a makeshift press, place a plate or a small cutting board on top of the curds and then place your weight (such as a heavy pot or a stack of books) on top of the plate.

As the tofu presses, you’ll see the whey draining out of the mold. This is a good sign—it means the curds are compacting and the tofu is firming up. If the whey stops draining before the tofu has reached your desired firmness, you can try increasing the pressure slightly or gently loosening the curds around the edges of the mold to encourage more drainage. Be patient, though—pressing tofu is a slow process, and rushing it can lead to uneven texture or even breakage.

Monitoring the Pressing Process

While the tofu is pressing, it’s a good idea to keep an eye on the process to ensure everything is going smoothly. If you notice that the whey is draining too slowly, it may indicate that the curds are too tightly packed or that the pressure is uneven. In this case, you can try gently loosening the edges of the tofu with a spoon or a knife to create channels for the whey to escape.

If, on the other hand, the whey is draining too quickly, it may suggest that the pressure is too high or that the curds are not compacting properly. In this case, you can try reducing the pressure slightly or even removing the weight for a few minutes to allow the curds to settle. The key is to find a balance where the whey is draining steadily but not so quickly that the tofu becomes dense or rubbery.

As the tofu presses, you may also notice that the shape of the tofu block is changing. This is normal, as the curds are compacting and the whey is being expelled. If you’re aiming for a specific shape, such as a square or a rectangle, you can gently guide the tofu into the desired form as it presses. Just be careful not to handle the tofu too much, as it can be quite delicate at this stage.

Removing and Storing the Tofu

Once the tofu has been pressed to your desired firmness, it’s time to remove it from the mold. This can be a bit tricky, especially if the tofu is very soft or if it’s stuck to the sides of the mold. The key is to be gentle and patient, to avoid breaking the tofu or leaving chunks behind.

Start by carefully loosening the edges of the tofu with a spoon or a knife. Gently run the utensil around the perimeter of the tofu, separating it from the sides of the mold. If you’re using a traditional tofu press with a removable bottom, you can simply lift the mold off the tofu. If you’re using a colander or a makeshift mold, you may need to invert the mold onto a plate or a cutting board and gently tap the sides to encourage the tofu to release.

Once the tofu is out of the mold, transfer it to a container of cold water. This will help to firm up the tofu slightly and rinse off any residual whey or coagulant. Let the tofu soak in the water for a few minutes, then carefully lift it out and place it on a clean kitchen towel or a piece of cheesecloth. Pat the tofu dry gently, being careful not to press too hard, as this can damage the delicate structure of the tofu.

Storing Your Homemade Tofu

Freshly made tofu is a beautiful thing, but it’s also highly perishable. To extend its shelf life, it’s important to store it properly. The best way to store homemade tofu is in a container of fresh, cold water. The water should completely cover the tofu, which will help to keep it moist and prevent it from drying out. You can add a pinch of salt to the water, which will help to preserve the tofu and enhance its flavor.

Place the container of tofu and water in the refrigerator, where it will keep for up to a week. Change the water daily to keep the tofu fresh and to prevent any off flavors from developing. If you notice that the water is becoming cloudy or that the tofu is developing a sour smell, it’s a sign that the tofu is starting to spoil and should be discarded.

If you’ve made a large batch of tofu and want to extend its shelf life even further, you can freeze it. To freeze tofu, drain it well and pat it dry, then wrap it tightly in plastic wrap or place it in an airtight container. Frozen tofu will keep for up to three months, though the texture may change slightly upon thawing. Frozen tofu tends to become more porous and spongy, which can actually be desirable for certain dishes, such as stir-fries or stews, as it absorbs flavors more readily.

Troubleshooting Common Issues

Even with the best intentions and careful attention to detail, things can sometimes go wrong in the tofu-making process. Maybe your soy milk didn’t coagulate properly, or perhaps your tofu turned out too soft or too firm. Don’t worry—these issues are common, and most of them can be easily fixed with a bit of troubleshooting.

One of the most common issues is soy milk that won’t coagulate. If you’ve added your coagulant and waited the appropriate amount of time, but the soy milk is still liquid, there are a few possible culprits. First, check the temperature of the soy milk. If it’s too cold, the proteins may not be denaturing properly, which can prevent coagulation. Try heating the soy milk gently to bring it back up to the ideal temperature range of 160-175°F (71-80°C).

If the temperature is fine, the issue may be with the concentration of proteins in the soy milk. If the soy milk is too dilute, the proteins may be too spread out to bind together properly. In this case, you can try heating the soy milk gently to evaporate some of the liquid, which will concentrate the proteins and may allow coagulation to occur. Alternatively, you can try adding a bit more coagulant, though be cautious—adding too much can lead to overly firm or rubbery tofu.

Tofu That’s Too Soft or Too Firm

Another common issue is tofu that’s either too soft or too firm. If your tofu is too soft, it may be due to insufficient pressing or too little coagulant. To fix this, you can try pressing the tofu for a longer period of time, using a heavier weight or increasing the pressure gradually. You can also try adding a bit more coagulant to the soy milk before pressing, though this may not be effective if the tofu has already been pressed.

If your tofu is too firm, it may be due to over-pressing or too much coagulant. To prevent this, be sure to monitor the pressing process closely and remove the tofu from the press as soon as it reaches your desired firmness. You can also try using a bit less coagulant in your next batch, or diluting the soy milk slightly with a bit of water to reduce the protein concentration.

Finally, if your tofu has an off flavor or smell, it may be due to improper storage or contamination during the pressing process. Always be sure to store your tofu in fresh, cold water, and change the water daily to keep it fresh. If you notice any sour or unpleasant smells, it’s best to discard the tofu and start fresh with a new batch.

Experimenting with Flavors and Textures

Once you’ve mastered the basic process of making tofu from roasted soybeans, the real fun begins—experimenting with different flavors and textures. There are countless ways to customize your tofu, from infusing the soy milk with herbs and spices to adjusting the pressing process to achieve unique textures. The possibilities are truly endless, and half the joy of making tofu at home is the ability to tailor it to your exact preferences.

One of my favorite ways to experiment with tofu is by infusing the soy milk with different flavors. This can be as simple as adding a few cloves of garlic or a sprig of rosemary to the soy milk as it heats, or as complex as creating a custom spice blend to complement a specific dish. The key is to add the flavorings early in the process, so they have time to infuse into the soy milk before coagulation. Just be sure to strain out any solids before adding the coagulant, as they can interfere with the curd formation.

Another fun way to customize your tofu is by playing with the pressing process. As we’ve discussed, the amount of pressure applied and the duration of pressing will determine the firmness of your tofu. But you can also experiment with different pressing techniques to achieve unique textures. For example, you can try pressing the tofu in stages, starting with a gentle pressure and gradually increasing it to create a layered texture. Or, you can try pressing the tofu in a shaped mold to create fun, decorative tofu for special occasions.

Adding Mix-Ins

Finally, don’t be afraid to get creative with mix-ins. Once your tofu is pressed and ready to go, you can fold in all sorts of delicious additions to take it to the next level. Chopped herbs, toasted nuts, dried fruits, and even crumbled cheese can all add a burst of flavor and texture to your homemade tofu. The key is to choose mix-ins that complement the nutty, slightly sweet flavor of the roasted soybeans and that will hold up well to the pressing process.

One of my favorite mix-ins is toasted sesame seeds. The nutty flavor of the sesame pairs beautifully with the roasted soybeans, and the seeds add a delightful crunch to the tofu. To incorporate mix-ins, simply fold them gently into the pressed tofu before storing or cooking. Be careful not to overmix, as this can break up the delicate structure of the tofu.

Cooking with Homemade Tofu

Now that you’ve put in the time and effort to make your own tofu from roasted soybeans, it’s time to enjoy the fruits of your labor. Homemade tofu is incredibly versatile and can be used in a wide variety of dishes, from stir-fries and soups to salads and sandwiches. The nutty, slightly sweet flavor of tofu made from roasted soybeans pairs particularly well with bold, savory ingredients, such as soy sauce, garlic, and ginger.

One of my favorite ways to enjoy homemade tofu is in a simple stir-fry. The firm texture of pressed tofu holds up beautifully to the high heat of the wok, and the nutty flavor of the roasted soybeans shines through the savory sauce. To make a quick and easy tofu stir-fry, simply cube your tofu and pan-fry it in a bit of oil until golden and crispy. Then, add your favorite stir-fry vegetables and sauce, and toss everything together until the veggies are tender and the tofu is coated in the delicious sauce.

Another great way to use homemade tofu is in a comforting bowl of miso soup. The soft, silky texture of the tofu is perfect for soaking up the savory, umami-rich broth, and the nutty flavor of the roasted soybeans complements the earthy miso paste beautifully. To make a simple miso soup with tofu, start by simmering a pot of dashi (Japanese soup stock) with a bit of soy sauce and mirin. Then, add cubes of tofu and your favorite miso soup ingredients, such as wakame seaweed, scallions, and mushrooms. Simmer everything together until the tofu is heated through and the flavors have melded together.

Baking and Grilling Tofu

Finally, don’t overlook the potential of baked or grilled tofu. The firm texture of pressed tofu makes it ideal for these dry-heat cooking methods, and the nutty flavor of the roasted soybeans takes on a delicious depth when exposed to the high heat of the oven or grill. To bake or grill tofu, start by pressing it well to remove as much moisture as possible. Then, marinate the tofu in your favorite sauce or seasoning blend for at least 30 minutes, or up to overnight. This will allow the flavors to penetrate the tofu and create a delicious crust when cooked.

To bake the tofu, place it on a lined baking sheet and bake at 400°F (200°C) for about 20-25 minutes, flipping halfway through, until the tofu is golden and crispy. To grill the tofu, place it on a well-oiled grill grate and cook for about 3-5 minutes per side, until the tofu is heated through and has beautiful grill marks. Serve the baked or grilled tofu as a main dish, or slice it and use it in sandwiches, salads, or grain bowls.

Conclusion

Making tofu from roasted soybeans is a labor of love, but the results are truly worth the effort. There’s something incredibly satisfying about transforming a humble soybean into a delicious, nutritious block of tofu, and the flavor and texture of homemade tofu are simply unmatched by store-bought versions. Plus, the process itself is a fascinating exploration of the science of food, from the Maillard reaction during roasting to the protein coagulation during pressing.

As with any new skill, don’t be discouraged if your first few attempts don’t turn out perfectly. Tofu-making is as much an art as it is a science, and it takes time and practice to develop a feel for the process. Keep experimenting with different techniques, flavors, and textures, and don’t be afraid to make mistakes—some of the best discoveries in the kitchen come from happy accidents.

So, what are you waiting for? Grab some soybeans, fire up your oven, and get ready to embark on a delicious tofu-making adventure. And remember, the journey is just as important as the destination. Happy tofu-making!
