Thank you for those sources!
I have a question regarding one of them. It quotes Rav Moshe as saying that “foods which were not consumed by Jews at the time the minhag of kitnios began are not forbidden on Pesach.” In that case, corn (maize), being native to the New World only, would be permitted on Pesach because the kitniyot prohibition predates Columbus by a few centuries. Does that mean I can enjoy corn and corn derivatives on Pesach?
