Tofu, also called bean curd, is made by curdling soy milk in a process similar to cheese-making.
Although it is almost tasteless by itself, tofu acts like a sponge, easily absorbing other flavors.
Look for tofu in the produce section of your grocery store, although some stores sell it in the deli or dairy department. Check the "sell by" date on the package to ensure freshness. Store tofu in the refrigerator (unless it is an aseptic package). Once opened, refrigerate tofu covered with water for up to one week, changing the water daily. Tofu can also be frozen for up to five months.
