My Dad introduced me to Jicama the last time I was down to NY, and to my surprise it’s tasty and very edible for me. The consistency is similar to that of a potato but it’s sweet and not nearly as starchy. I’ve been putting it in salads, frying it up to serve as the base for sauce-based dishes like indian food, and snacking on it raw. It’s really better raw than it is cooked but either way works. I found a recipe for mashed potatoes using it as the base that I’m going to try soon. It’s also very cheap, and at least locally is easy to come by.
