This question already has an answer here:
- Corn as kitniot 1 answer
Was reading halakhic discourse given here that said the following:
In later generations, the Ashkenazi Poskim discuss whether other foods, such as coffee beans, peanuts and quinoa, would also be considered “Kitniyot.” Rav Shlomo Amar and Rav Moshe Feinstein rule that any food that wasn’t known in the Western world at the time of the original institution of the Gezera was not included in the custom.
However, corn is a new world crop, and when the Gezera was instituted no one would have even known corn existed. So if the halakhic justification that allows Ashkenazim to use coffee beans and cocoa beans (chocolate) during Pesach is that new world foods don't count as "kitniyot", then why is corn forbidden?
