So I picked up a couple cactus pears at my grocery store because, well, why not. They were there and I had never eaten them. But my local grocer had no idea what to do with it, how to prepare it, or even what it tastes like (sweet? sour?). So, can someone please tell me how to prepare it (I assume I peel it - what's the best way to do that?) and anything else about this? Thanks!
