My MIL gave me these two fruits/vegetables saying she picked them up at an open market and that they were "sweet potatoes." Now, obviously that is NOT what they are (a lot of French people are very unclear on what sweet potatoes are, even though they ARE available here), so the question is, what in fact is this? I am thinking it is a chayote, but I have never bought one of those before, so if that is what it is, what should I do with it? Any help would be greatly appreciated! I did look at previous threads, but I guess I was hoping to get some TNT simple recipes as well as a confirmation that this IS in fact a chayote. Also, do I peel it? Seed it?
