Your 'i' is wrong, Cloverjo. 22d is not pirogi, but something similar (and not just an alternative way of pluralising the thing as I initially thought).
Cloverjo,thanks - but I came back on to apologise, there isn't a clash. I think I have tackled too many puzzles with those this weekend! Your I, as Rick says, is wrong. Your As is the 'like' in the clue, so your extra letter relates to the earlier part of the clue...
