If you recall the actual story of Doublemeat Palace Buffy made her most stupefying mistake when she found out that no meat was used, only fat drippings from the animal in a vegetable matrix. She could have shaken down Doublemeat Palace for enough money to pay all her bills and get her a full ride through university. If they stayed true to their process, there would be as little demon meat in the patty as there was beef so maybe there would be no problem for most people.
I did some googling, and most cannibals say it tastes like either veal or pork...
Googling...yeah, sure. What is that you're chewing...? 😱
