Ok, so, I'm not sure what to make of this. John Vescio sent me a link to a product called HuFu which, according to the HuFu FAQ, "is designed to resemble, as humanly possible, the taste and texture of human flesh" while actually containing "no human or animal products". Got it? It's a vegan product that tastes like human flesh. The site isn't graphic, but still, you may not want to go read more.
TM Lutas thinks HuFu is in poor taste. He also makes a larger point about taboos existing for a reason, and I agree (isn't that part of being "conservative"?); cannibalism is a particularly valuable taboo, in my humble opinion.
