Last year, I wrote about guidelines for deciding what is kitniot and said that in my opinion everybody should think about the issue of kitniot and make her/his own list of things that she/he considers kitniot. So the obvious follow-up question is: What do you decide?
Well. First, I do decide that I want to honor the minhag somewhat, so there are things that I do not eat on pessach because I consider them kitniot. Second, I decide that (a) I think there should not be additions to the original list, but (b) there should be some botanical consistency to the list.
So effectively my list includes the "original" kitniot (i.e., beans, peas, lentils, chickpeas, rice, millet, buckwheat) and additionally things that are botanically cereal grains (maize/corn, rice, millet). Yes, I would definitely eat quinoa (that is, if I ever ate quinoa, which I really don’t).
