Tofu is an essential ingredient in Chinese cuisine. It’s made from soybeans and has been enjoyed for centuries for its versatility and nutritional benefits. Tofu can be used in a variety of dishes, from soups and stir-fries to desserts and snacks. In this article, we will explore how to make Chinese tofu at home, covering everything from selecting the right soybeans to the various methods of preparing and cooking tofu. The process is straightforward, and with the right ingredients and steps, you can enjoy fresh, homemade tofu.
What is Tofu?
Tofu, also known as bean curd, is made by coagulating soy milk and pressing the curds into solid blocks. It is high in protein and a great source of calcium, making it a popular choice for vegetarians and vegans. Tofu has a mild flavor, which makes it an excellent ingredient for absorbing the flavors of the dishes it is cooked with.
There are different types of tofu, including silken tofu, soft tofu, firm tofu, and extra-firm tofu. Each type is suited for different types of dishes. Silken tofu is smooth and soft, making it great for soups and desserts. Firm tofu holds its shape well and is ideal for stir-fries and grilling.
Ingredients Needed to Make Tofu
To make Chinese tofu, you will need the following ingredients:
Soybeans – The main ingredient for making tofu is soybeans. Choose non-GMO, organic soybeans if possible for the best quality tofu.
Coagulant – A coagulant is needed to curdle the soy milk. There are two main types of coagulants used in tofu making: magnesium chloride (nigari) and calcium sulfate (gypsum). You can choose either, depending on your preference.
Water – Water is required for soaking the soybeans and making soy milk.
Optional Flavoring – Some people add a little salt or other flavoring to the tofu during the pressing stage to enhance its taste, but this is not necessary.
Step 1: Soaking the Soybeans
The first step in making tofu is to soak the soybeans. Soaking softens the soybeans, making them easier to blend and extract the soy milk.
- Take 1 cup of dried soybeans and rinse them thoroughly under cold water to remove any dirt or impurities.
- Place the soybeans in a large bowl and cover them with plenty of water. The soybeans will expand as they soak, so make sure to add enough water.
- Let the soybeans soak for at least 12 hours, or overnight, at room temperature. If you’re in a hurry, you can soak them for 6 hours, but overnight soaking gives the best results.
Step 2: Making Soy Milk
After the soybeans have soaked, the next step is to make soy milk. This is done by blending the soybeans with water and then straining out the pulp.
- Drain the soaked soybeans and place them in a blender.
- Add 3-4 cups of fresh water to the blender with the soybeans.
- Blend the soybeans and water together until you have a smooth, creamy mixture.
- Place a fine-mesh strainer or cheesecloth over a large pot or bowl. Pour the blended soybean mixture into the strainer to separate the soy milk from the soybean pulp (called okara).
- Squeeze the cheesecloth to extract as much soy milk as possible. The remaining okara can be saved for other recipes, like baking or making vegan burgers.
- You should now have around 4 cups of fresh soy milk.
Step 3: Coagulating the Soy Milk
Next, you need to add a coagulant to the soy milk to curdle it and form tofu curds. The most common coagulants are magnesium chloride (nigari) or calcium sulfate (gypsum). Both work well, but nigari tends to create softer tofu, while gypsum results in firmer tofu.
- Dissolve 1-2 teaspoons of your chosen coagulant in about 1/4 cup of warm water. Stir until it is completely dissolved.
- Heat the soy milk over medium heat in a large pot, stirring occasionally to prevent it from burning. Bring it to a gentle boil, then reduce the heat.
- Slowly pour the coagulant mixture into the hot soy milk while gently stirring. Make sure to pour it evenly across the soy milk surface.
- Let the soy milk sit undisturbed for about 5-10 minutes. You will see the curds begin to form, and the liquid will start to separate into curds and whey.
Step 4: Draining the Tofu
Once the curds and whey have separated, it’s time to drain the tofu.
- Line a tofu mold or a small rectangular container with cheesecloth. If you don’t have a tofu mold, you can use any container with drainage holes (such as a small colander).
- Gently ladle the tofu curds into the mold, allowing the whey to drain through the cheesecloth.
- Fold the cheesecloth over the top of the curds to cover them. This will help with pressing the tofu later.
Step 5: Pressing the Tofu
Pressing the tofu removes excess whey, giving the tofu its desired texture. The more you press it, the firmer the tofu will be.
- Place a weight or something heavy, such as a can or a jar, on top of the wrapped tofu to press it. The weight should be evenly distributed to apply steady pressure.
- Let the tofu press for 15-30 minutes, depending on how firm you want the tofu to be. For soft tofu, you can press it for just 15 minutes, but for firm tofu, press it for up to 30 minutes.
- After pressing, carefully unwrap the cheesecloth and remove the tofu from the mold. You now have fresh, homemade tofu!
Step 6: Storing Your Tofu
To store your homemade tofu, place it in a container with fresh water. Be sure to change the water daily to keep it fresh. Homemade tofu will last about 3-4 days in the refrigerator.
If you want to keep it for a longer period, you can freeze the tofu. Freezing will change the texture, making it more spongy and firm once thawed. This can be ideal for certain dishes, like stir-fries, where a firmer texture is preferred.
Cooking and Serving Your Tofu
Once you’ve made your tofu, you can use it in a variety of Chinese dishes. Here are a few ideas for cooking with tofu:
Stir-Fried Tofu: Slice the tofu into cubes or slabs and stir-fry it with vegetables, soy sauce, garlic, and other seasonings for a simple, delicious meal.
Mapo Tofu: This is a popular Sichuan dish where tofu is cooked in a spicy, flavorful sauce made with ground pork or beef, chili paste, and fermented bean paste.
Tofu Soup: Silken tofu is perfect for soups, such as the classic Chinese hot and sour soup, where it adds a smooth texture to the broth.
Tofu Scramble: For a vegan alternative to scrambled eggs, crumble tofu and cook it with spices, vegetables, and a little turmeric for color.
Grilled Tofu: Firm tofu can be marinated in soy sauce, sesame oil, and other spices, then grilled for a smoky flavor.
Conclusion
Making Chinese tofu at home is an easy and rewarding process. By following these steps, you can create fresh, delicious tofu that can be used in a variety of dishes. With just a few ingredients and some patience, you can enjoy homemade tofu that is healthier and more flavorful than store-bought options. Tofu is not only a great source of protein but also a versatile ingredient that can be cooked in numerous ways to suit your tastes. Whether you prefer it soft and creamy in soups or firm and crispy in stir-fries, homemade tofu is sure to enhance your Chinese cooking experience.
