Noun
1. a protein-rich food made from curdled soybean milk, by coagulating it with magnesium sulfate.
Tofu, also called Doufu (often in Chinese recipes) or bean curd (literal translation), is a food of Chinese origin, made by coagulating soy milk, and then pressing the resulting curds into blocks. The making of tofu from soy milk is similar to the technique of making cheese from milk. Wheat gluten, or seitan, in its steamed and fried forms, is often mistakenly called “tofu” in Asian or vegetarian dishes.

Have a mouth as sharp as a dagger, but a heart as soft as tofu.
~ Chinese Proverb
