Eden Dried Tofu is from freshly made firm tofu using only whole, non GEO soybeans, and "nigari", a high magnesium mineral salt used to coagulate soymilk into tofu. The tofu is made in the traditional manner used for centuries. After the tofu is made it is cut into blocks and frozen for 20 days. After defrosting the tofu is pressed to remove water, sliced and naturally air dried before packaging.
