Firm tofu is a type of soy product made from coagulated soy milk, pressed into solid blocks. It has a denser texture compared to softer varieties, making it ideal for stir-frying, grilling, or baking. Firm tofu holds its shape well during cooking, allowing it to absorb flavors from marinades and sauces. Rich in protein and low in calories, firm tofu is a popular choice for vegetarians and vegans. It is also a good source of essential amino acids, iron, and calcium. This versatile ingredient can be used in a variety of dishes, from salads to soups, enhancing both nutrition and taste.
