Tofu is a popular soy-based food that originated in China. It is made by coagulating soy milk and then pressing it into solid blocks. Tofu has a mild flavor, a texture similar to cheese or pudding, and is high in protein and other essential nutrients. It can be eaten on its own or used as an ingredient in various dishes such as stir-fries, salads, soups, and sandwiches. Tofu is also a good source of calcium, iron, and vitamin B12.
