Stuff We Wished Existed But Doesn't ... Or Maybe It Does: Hufu

From Wikipedia:

Hufu is a supposed tofu-based product that is meant to resemble, as realistically as possible, the taste and texture of human flesh. It is not known at present if the product actually exists, or has existed, and as such, Hufu has been alleged to be real.

Until the recent closure of the Hufu web site, Hufu was touted as "the healthy human flesh alternative" for "cannibals who want to quit", as well as a product for anthropology students studying cannibalism. The morbidly humorous nature of the product and its official descriptions led many Internet users to suspect that Hufu was little more than a prank on the part of its creator.

Mark Nuckols (founder and CEO of Hufu, LLC)—then a student at Tuck School of Business—claimed that the concept of Hufu occurred to him while reading anthropologist Marvin Harris' "Good To Eat: Riddles of Food and Culture" and simultaneously eating a tofurkey sandwich.

Some customers believed Hufu to be a scam, and the actual product to be nonexistent. This theory was supported by the sudden and unannounced closure of the Hufu home page as of mid 2006. However, according to Mark Nuckols, he closed the website simply because "the world has moved on past hufu, and the site was more expensive to run than it was worth."

Worth tossing in, of course, is the line from Futurama regarding the taste of Soylent Cola: "It varies from person to person."
