Okay, So What is Tofu, Exactly?
Tofu, also known as bean curd, is a versatile vegan food that has been a staple in Asian cuisines for centuries. Made from soybeans, tofu is valued for its high protein content, versatility, and mild flavor that readily absorbs other flavors and seasonings.
Tofu comes in various forms, including silken, soft, firm, and extra-firm, each with its own unique texture and culinary applications.
A Brief History of Tofu: From Ancient China to Global Phenomenon
Tofu’s journey through history is as rich as its culinary uses. The story begins in ancient China, where (legend has it) its discovery was a happy accident.
As the story goes, a Chinese cook accidentally curdled soy milk with nigari, a natural coagulant derived from seawater, and that mistake resulted in the creation of tofu. While the exact origins of tofu remain a mystery, historical records note its first use in China during the Han dynasty (206 BCE – 220 CE).
Originally known as “doufu” in Chinese, tofu quickly gained popularity as a nutritious and affordable source of protein, particularly among Buddhist monks who followed vegetarian diets. From China, tofu spread to neighboring countries such as Japan, Korea, and Vietnam, where it became an integral part of their traditional cuisines.
How Tofu is Made
Tofu is made through the process of curdling. Fresh soy milk is combined with a coagulant, and the resulting curds are pressed into blocks.
The soy milk is made by soaking and grinding soybeans. The liquid extracted from the beans is then heated and combined with a chemical that binds the proteins together, such as calcium sulfate or magnesium chloride.
Finally, the curds are separated from the whey, pressed into molds, and left to set, resulting into blocks of tofu. The firmness of the tofu depends on how much water is pressed out of the curds.

Tofu in aseptic packaging (like silken tofu) is shelf stable until opened. Be sure to refrigerate immediately and use within 1-2 days. - How to prepare tofu for cooking: Drain the tofu and press out excess water. You can use a tofu press, or sandwich the block in cheesecloth between two weighted plates to extract as much water as possible.
