Tofu 101: Everything You Need To Know About Tofu


Tofu, also known as bean curd, is a versatile and nutrient-rich food that has been a staple in Asian cuisine for centuries. In recent years, its popularity has surged worldwide due to its health benefits and adaptability to various dishes. This comprehensive guide delves into the origins, types, nutritional benefits, and culinary uses of tofu, providing everything you need to know about this remarkable ingredient.

The origins of tofu

Tofu’s history dates back over 2,000 years to ancient China. The Han Dynasty (206 BCE–220 CE) is believed to have discovered tofu. The legend attributes its invention to Prince Liu An, who accidentally created tofu while experimenting with soy milk coagulation. From China, tofu spread to Japan, Korea, and eventually the rest of the world, becoming a beloved component of many global cuisines.

How it is made?

Curdling soy milk and pressing the curds into soft or hard blocks creates soy-based foods like tofu. It comes from China and has been an important part of East Asian cooking for hundreds of years. Making tofu is a very interesting process. Soak the soybeans and then grind them to obtain the soy milk. Next, we use natural coagulants like calcium sulfate or magnesium chloride to heat the soy milk and thicken it. Once ready, we press the curds to remove excess liquid and shape them into blocks.

Another amazing thing about tofu is that it can take on tastes. Tofu’s porous texture lets marinades and spices soak in easily, making it a great base for many kinds of food. You can use tofu in a variety of ways, such as stir-frying, grilling, or even making soups.

Types of tofu

Silken tofu

Silken tofu, also known as Japanese-style tofu, has a smooth and creamy texture. It is undrained and unpressed, which results in a high moisture content. Silken tofu is delicate and can easily crumble, making it ideal for smoothies, desserts, soups, and dressings.

Soft tofu

Soft tofu is similar to silken tofu but slightly firmer. It retains a high moisture content, making it perfect for dishes that require a softer texture, such as stews and casseroles. You can also substitute soft tofu for silken tofu to achieve a slightly firmer texture.

Firm tofu

Pressing firm tofu removes some of its water content, giving it a denser texture. You can use it in a variety of dishes, from stir-fries to grilling, due to its versatility. Firm tofu holds its shape well and absorbs marinades effectively, making it a popular choice for savory recipes.

Extra-firm tofu

Extra-firm tofu has the least amount of moisture and the densest texture. It is perfect for grilling, frying, and baking because it maintains its shape during cooking. Dishes that require a meaty texture, like tofu burgers or kebabs, often use this type of tofu.

Super-firm tofu

Super-firm tofu is the most compact type available. It has an extremely dense texture, almost resembling meat in its firmness. Super-firm tofu is excellent for slicing, dicing, and marinating. It is a great choice for recipes that call for a substantial, chewy texture.

Tofu has nutritional benefits.

Tofu is not only versatile but also highly nutritious. It is an excellent source of protein, making it a staple for vegetarians and vegans. Tofu presents several key nutritional benefits.

  • High in Protein: Tofu is considered a full-protein source as it contains all nine essential amino acids. In a 100-gramme portion of tofu, there are around 8 grammes of protein.
  • Low in Calories: Tofu is relatively low in calories, making it a great option for those looking to maintain a healthy weight.
  • Rich in Minerals: Tofu is a good source of calcium, iron, and magnesium. These minerals are essential for bone health, oxygen transport, and muscle function.
  • Contains Isoflavones: Tofu is rich in isoflavones, which are plant compounds that have antioxidant properties. Researchers have linked isoflavones to various health benefits, such as a reduced risk of heart disease and certain cancers.
  • Low in Saturated Fat: Tofu is low in saturated fat and contains no cholesterol, making it heart-friendly and suitable for those managing cholesterol levels.

Is it vegan and keto friendly?

Absolutely! Because tofu is made from soy beans, it is meatless, vegan, gluten-free, and good for people on the keto diet. You should know that some store food is seasoned and may contain wheat. Before you buy any, you should always read the packages. 

Culinary uses of tofu

A wide range of dishes can incorporate tofu due to its neutral flavor and diverse textures. Here are some popular culinary uses for tofu:

Tofu in stir-fries

Firm and extra-firm tofu are excellent choices for stir-fries. They absorb sauces and marinades well, enhancing the overall flavor of the dish. To prepare tofu for stir-frying, press it to remove excess water, then cut it into cubes or slices. Marinate the tofu before adding it to your stir-fry for best results.

Soups and stews with tofu

Soft and silky tofu is ideal for soups and stews. Their delicate texture blends well with the broth, adding a creamy consistency to the dish. Japanese miso soup commonly uses silken tofu, while Korean sundubu-jjigae (soft tofu stew) uses soft tofu as a key ingredient.

Tofu in salads

Tofu can be a great addition to salads, providing a protein boost and a satisfying texture. Firm or extra-firm tofu works best in salads. You can pan-fry, bake, or grill the tofu before adding it to your salad for added flavor and texture.

Tofu substitutes for meat.

Tofu’s versatility makes it an excellent meat substitute in many recipes. Use extra-firm or super-firm tofu in dishes like tofu burgers, tacos, and kebabs. You can crumble tofu to resemble ground meat in dishes like tacos or spaghetti sauce.

Tofu in desserts

Silken tofu is perfect for desserts due to its smooth and creamy texture. You can use it to create dairy-free puddings, mousses, and cheesecakes. You can also blend silken tofu into smoothies to create a protein-rich and creamy treat.

How to store tofu

Proper storage is essential to maintaining tofu’s freshness and quality. Here are some tips for storing tofu:

  • Refrigeration: Store the tofu in its original packaging in the refrigerator until you open it. Once opened, transfer the tofu to a container with fresh water and change the water daily. Use within 3–5 days.
  • Freezing: You can freeze it. Freezing changes the texture, making it chewier and more porous, which can be desirable for certain recipes. Drain and press the tofu before freezing. Store it in an airtight container or freezer bag for up to 3 months. Thaw in the refrigerator before use.

The bottom line

Tofu is a nutritious, versatile, and delicious ingredient that can enhance a variety of dishes. Whether you are a seasoned tofu enthusiast or a newcomer, experimenting with different types of tofu can open up a world of culinary possibilities. From stir-fries and soups to salads and desserts, tofu’s adaptability makes it a valuable addition to any kitchen.
