Tofu

What is Tofu?

Tofu is made by curdling soy milk and pressing the curds into solid, white blocks. The texture can range from silken and soft to firm or extra firm, depending on how much water is pressed out. It has a mild, neutral flavor, making it adaptable to many dishes. Tofu is rich in protein and low in calories, and its appearance is usually a smooth, pale block. It is used in soups, stir-fries, salads, and desserts across East and Southeast Asia.

Where does Tofu come from?

Tofu originated in China, with records dating back over two millennia to the Han dynasty. Chinese legend credits its invention to Prince Liu An, though this is debated. The technique spread to Japan, Vietnam, and other parts of Asia, often alongside the spread of Buddhism, since tofu is an important protein source in vegetarian diets. By the Song dynasty, tofu became popular in China, and later, it was introduced to Western countries, where it gained recognition as a meat substitute.

How is Tofu made?

The process begins by soaking and grinding soybeans, then boiling and filtering them to produce soy milk. A coagulant—such as calcium sulfate (gypsum), magnesium chloride (nigari), or glucono delta-lactone—is added to curdle the milk. The curds are then pressed into molds to form blocks. The firmness depends on the amount of water removed and the type of coagulant used. Some varieties, like silken tofu, are not pressed and remain very soft.

How and when is Tofu eaten?

Tofu is eaten in many ways, depending on the region and dish. It can be served raw, simmered in soups, stir-fried, deep-fried, or even used in desserts. Its neutral taste allows it to absorb the flavors of sauces and seasonings. Tofu is a daily food in many Asian households and is found in street food stalls, restaurants, and home kitchens. It is valued for its versatility and nutritional content.

Kinds of Tofu

There are many types of tofu, distinguished by texture and preparation. Silken tofu is soft and smooth, often used in soups or desserts. Firm and extra firm tofus hold their shape better and are suited for stir-frying or grilling. Regional differences exist: in China, tofu may be softer; in Japan, both silken and firm types are common. Southeast Asian countries have their own versions, sometimes with added flavors or spices.

What Tofu means

Tofu is deeply rooted in the food cultures of East and Southeast Asia. In China, it was once offered at graves, believed to be soft enough for ancestral spirits. Tofu's spread is linked to the growth of Buddhism, as it provides protein for vegetarian diets. In Japan, tofu has been featured in cookbooks since the Edo period. Today, tofu is recognized worldwide as a sustainable, plant-based protein source.
