Tofu is made in the Chinese province of Anhui, and it has been consumed in China for almost 2,000 years, dating back to the Han dynasty. Hairy Tofu (tofu that has been left outside to ferment until it develops hairs) is a Chinese delicacy prepared in the mountains of Anhui. The texture is similar to that of blue cheese. It's not eaten raw; it's dipped in an egg yolk batter, fried, and then dipped in sauce.
