Tofu is a unique vegan product, similar to cheese in texture, and made out of coagulated soy milk. The process of coagulation separates the curd from the whey, which results in the formation of protein-packed soy curds which are stored in containers to retain a rectangular shape, making it readily available for further use.
Most tofu varieties are created by the process of coagulation, but might differ in how hey are stored and drained, which affects the texture of the final product. The primary distinction is made between firm and soft tofu, which are used according to their composition and characteristics.
It is usually cubed or sliced, marinated, and can be grilled, fried, barbecued, boiled, and used in a seemingly limitless variety of dishes. Soft tofu, often referred as the silken tofu, has a higher percentage of moisture and is usually not drained.
Its consistency is smooth and tender, and it is often eaten on its own, accompanied by a variety of sweet and savory condiments. The origin of tofu is said to have happened in China, and the man who is usually associated with its invention is the prince Liu An of the Han dynasty, who presided over the prefecture Huai'an.
This theory has been widely disputed, but the fact remains that tofu has been consumed in ancient China as early as the 2nd century BC. From China, it has spread throughout Asian countries, primarily Japan, Korea, Vietnam, and Thailand, where it became a staple ingredient.
