Karelian pies is more commonly used.
My thoughts exactly.
Waaaaaait, I think you've been teaching "karjalanpiirakka" as Karelian pie, and now it is suddenly a pastry. Please, add pies to correct answers. Reported.
Would Karelian pirogi or pirogies not also be accepted?
Pasties mean something else on America.
Heheh. Must look these up. Are they anything like a Cornish? I do love a Cornish Pasty (pasties, pl, short 'a') -- like Matfsg said, pasties (dancers in the know say it with a long 'a', from 'paste'), are something else ;p
