This is from the FAQ:
What does Hufu TM taste like? Does it taste like human flesh?
HufuTM is designed to resemble, as humanly possible, the taste and texture of human flesh. If you’ve never had human flesh before, think of the taste and texture of beef, except a little sweeter in taste and a little softer in texture. Contrary to popular belief, people do not taste like pork or chicken.
Who actually buys HufuTM?
HufuTM was originally conceived of as a product for students of anthropology hungry for the experience of cannibalism but deterred by the legal and logistical obstacles. However, our preliminary market research revealed the existence of a larger segment of the public that was interested in the availability of a legal and healthy human flesh substitute.
But if you wish to feel better (worse?) about the whole thing, the CEO and cook admits he has never sampled human flesh. I believe this to be tofu plus a clever marketing idea.
Thanks to John Wilson for the pointer.
