In Carrington's post last week on the Joy of Cooking versus New York Times Cookbook she recalled her parents' arguing over the proper pronunciation of the cheese-and-toast dish called Welsh rarebit.
My position for a long time was that it was "rarebit" because there is already something called "rabbit." But then someone explained to me that cheese sauce on toast is what's for dinner when a Welshman goes rabbit hunting. It's a subtle insult, unless you're Welsh, in which case it's a comment on the national marksmanship (or lack of persistence--I don't know which.)
That got me thinking about other food name insults. There's the Italian beverage called "Caffe Americano," which is perfectly good espresso watered down with hot water for the vulgar tastes of the tourists.
But then I ran out of examples. There are funny names (pope's nose, hamantaschen, nun's nipples, the imam fainted) and aspirational ones (Cuba libre), but insults? Anyone come up with the names of dishes that are insults?
