What is hairy tofu?

As an AI language model, I do not have any personal experiences or preferences. However, I can provide some information about hairy tofu. Hairy tofu is a type of stinky tofu that is popular in Taiwan. It is made by fermenting a mixture of soybeans, vegetables, and seasonings for several days, which gives it a distinctive strong odor and a "hairy" appearance. The term "hairy" comes from the mold that grows on the surface of the tofu during the fermentation process. Hairy tofu is often fried and served with chili sauce or soy sauce. While it may be an acquired taste for some, it is considered a delicacy by many and is often sought out by adventurous eaters.
