Binks, I was wondering the same thing because I've tried it more than once (lousy memory for what doesn't work!). I found a whole bunch of Internet pages, though, which talked about making a tart called "Tarte (insert pretentious French title here)" -- plainly, the French term has not been assimilated into everyday usage, and I reckon that has to be pretty much the sole criterion, pace the compilers who include innumerable nonce-words and ancient misprints in the big dictionaries and in certain word lists floating round the Internet.
(I'm now looking for a smiley that somehow conveys an expression of modest wisdom!)
Cheers,
Dave
