When thawed, it has a pleasing chewy texture, just right for dishes like stew and chili. However, like pasteurized dairy products, tofu can spoil. Tofu keeps for about a week in the refrigerator, longer in the freezer. Once opened, cover it with water and store it in an airtight container. For best results, change the water at least every other day.
Soy milk is the liquid from the cooked, mashed soybeans, before the product is curdled to form tofu.
Once relegated to the shelves of health-food stores, it is now available in most supermarkets. Keep opened soy milk in the refrigerator for up to a week. Use it in place of cow's milk in most recipes. Blend soy or cow's milk, fruit, ice and dry soy protein shake powder. When purchasing soy milk, read the label carefully.
