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.
Tofu
was first used in China around 200 B.C. Although the discovery of the process
for making tofu is lost to the ages, Chinese legend has it that the first batch
of tofu was created by accident. A Chinese cook added nigari to flavor a batch
of puréed, cooked soybeans; the nigari produced the curd that we know today as
tofu.
Buying & 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.
Tips For Using Tofu
Tofu
is for everyone – and it’s very high in protein and other nutrients. Soft tofu
that has been pureed with fruits or vegetables is a good first protein food for
infants. Toddlers can enjoy chunks of cooked tofu for snacks or meals.

Tempeh (pronounced TEM pay) is
a traditional Indonesian food. This chunky, tender cake of soybeans is consumed
daily in Indonesia, usually with rice as part of the main meal, or sometimes by
itself as a snack. In Indonesia, tempeh-making is a household art that varies
somewhat from home to home. Whole soybeans are usually mixed with a grain such
as rice or millet. A "starter"- usually a piece of tempeh from a
previous batch - is added to begin the fermentation process. In traditional
home-based tempeh-making, the mixture is wrapped in banana leaves and left to
ferment for 18 to 24 hours. In Western tempeh factories, commercial starters
are used to produce tempeh, and the fermentation process takes place under
carefully controlled conditions. Whatever process is used, the result is a cake
of soybeans with a rich flavor sometimes described as smoky or nutty. The
flavor also has been compared to that of mushrooms.
Buying & Storing
Tempeh
Tempeh
is usually sold in natural food stores, where it is found in the frozen food or
refrigerated case. Frozen tempeh keeps well for several months. Tempeh can be
kept in the refrigerator for about 10 days. As with other aged or fermented
products, like cheese, a little mold on the surface of tempeh is harmless.
Using Tempeh
Tempeh
has a tender chewy consistency that makes it an excellent addition to a variety
of foods. It is delicious on the grill. First steam cubes of tempeh and
marinate them in a lemon marinade or a zesty barbecue sauce. Then grill until
browned. Add chunks of tempeh to spaghetti sauce, sloppy joes or chili mix, or
to favorite soups and casseroles. Steam and grate tempeh and mix with chopped
onions and celery and mayonnaise for a sandwich spread. Pan fry it with
mushrooms, onions and bread crumbs for a delightful mushroom stuffing.
Nutritional Value of Tempeh
Since
tempeh is made from whole soybeans, it is a fiber-rich food. It is also a
generous source of many nutrients such as protein, calcium, B-vitamins and
iron.
