Tofu, also known as soybean curd, is a soft, cheese-like food made by curdling fresh hot soymilk with a coagulant. Traditionally, the curdling agent used to make tofu is nigari, a compound found in natural ocean water, or calcium sulfate, a naturally occurring mineral. Curds also can be produced by acidic foods like lemon juice or vinegar. The curds then are generally pressed into a solid block.

Three main types of tofu are available in American grocery stores.

Firm tofu is dense and solid and holds up well in stir fry dishes, soups, or on the grill... anywhere that you want the tofu to maintain its shape. Firm tofu also is higher in protein, fat and calcium than other forms of tofu.

Soft tofu is a good choice for recipes that call for blended tofu, or in Oriental soups.

Silken tofu is made by a slightly different process that results in a creamy, custard-like product. Silken tofu works well in pureed or blended dishes. In Japan, silken tofu is enjoyed "as is," with a touch of soy sauce and topped with chopped scallions.

Buying and Storing Tofu:

Tofu most commonly is sold in water-filled tubs, vacuum packs, or in aseptic brick packages. Tofu is usually found in the produce section of the grocery store, although some stores sell tofu in the dairy or deli sections. Tofu is sometimes sold in bulk in food cooperatives or Asian markets. Unless it is aseptically packaged, tofu should be kept cold. As with any perishable food, check the expiration date on the package.

Once the tofu package is open, leftover tofu should be rinsed and covered with fresh water for storage. Change the water daily to keep it fresh, and use the tofu within a week.

Tofu can be frozen up to 5 months. Defrosted tofu has a pleasant caramel color and a chewy, spongy texture that soaks up marinade sauces and is great for the grill.

Here are some of the ways you can add tofu in your daily life.
