I'm looking for a short story I read probably 30 years ago.
The two main characters in the story were food designers who specialized in cultured meat grown from cells cloned from unlikely sources. They seemed almost like a cross between geneticists and fashion designers, producing new, interesting meats that would become trendy. I seem to recall that one of their hits was steak-sized meat cultured from lark's tongue cells.
At the end of the story they're presenting their latest creation, offering tastes but without saying what it is. The taster loves it. The twist, of course, is that it's cultured human flesh, a steak made from cells cloned from one of the main characters.
The ending might be a bit predictable but this was the first time I had heard of some of the ideas, and as a kid it was kind of mind blowing.
