I know perogi are eastern European in origin, but the name feels like a Welsh prank to me. I’ve seen like 8 or 9 distinct correct ways to spell pierogi, none of which I’d pronounce correctly if I didnt already know how to pronounce the word pierogue. Your piroghi pizza fills me with the jealousy of a man who loves potato and cheese but the rage of a man who hates being made to consider the word pirogi.
