Soy milk is a low-calorie substitute in recipes that call for milk, but check the label since many brands have added sweeteners. You'll find it in your dairy section or sold in aseptic cartons. You might want to buy single-serving sizes for easy use. Another fermented soy food, tempeh consists of soybeans that are mixed with mold, which holds the beans together, and then pressed into cakes. Tempeh has a chewy texture and a rich, yeasty flavor.
Some varieties are mixed with grains or vegetables during the fermentation stage.
You'll find tempeh in the refrigerated or frozen foods section of your grocery store. Check the expiration date stamped on the package. If you don't plan to use it straight away, you can safely store tempeh in your freezer. Tofu is the chameleon of the soy foods, and is so adaptable it can be pureed and used in fruit smoothies or sliced and stuffed with mixed vegetables, and baked. Sold in silken to extra-firm textures, tofu absorbs the flavors of whatever you prepare it with.
