I just got back from a trip to Mexico where I was fortunate enough to try a variety of foods. One of the things I really enjoyed trying was flat-leaved cactus (called nopal, I believe). They did all kinds of things with it. I was wondering if anyone in new of a place in the northern virginia/DC area knew of a place where I could find this. I'd like to try cooking with it. Perhaps a good latin market? I've never been to one.
