For further reading on confusing things...

Please see Commentary on Kitniyot which has some very good information on one aspect of "is not allowed" versus "is allowed but resembles something not allowed". I tend to agree with Rabbi Lerner and Benjamin Ben-Baruch here and come Passover will be trying out the suggestions there. As opposed to being the gentile would-be Jew trying to get the born Jewish but you'd never know it wife and mother-in-law to even look at the calendar. (Is it a good thing or a bad thing that our grocery schedule versus eating is so out of whack you're sometimes hard pressed to find any chametz in our house any time of the year or even just matzah? That was rhetorical.)

HOWEVER... Watch out which beans you serve and how many and perhaps, discretely of course, checking with your rabbi about Beano. You know, for your family's sake. :)
