Tofu is a block of pressed soybean curd. Like many things, tofu originated in China and figures in Chinese and Japanese cuisine, as well as being coveted by vegetarians of all nationalities for its high protein (and nonexistent cholesterol).

Neutral-tasting tofu tends to take on the flavor of whatever it's cooked with, kind of like chicken. It comes in many guises, including soft and firm, dried and processed.

A versatile ingredient, tofu can be eaten raw, cubed and marinated and added to salads or stir-fried dishes at the last minute (it holds its shape but must be treated with some delicacy). Or it can be cut into slices and fried until crispy. Tofu can also be mashed up and used to make non-dairy desserts, like "cheese"-cake.
