I'd like to introduce a veggie-hating friend to beets. He grew up in a house with one basic recipe for vegetables - open can, dump, boil vigorously. It left culinary scars. I've slowly been showing him how properly cooked vegetables are wonderful. Now, he's actually requested to try beets, but that's not a vegetable I usually cook. I don't want to blow this chance, so what are best recommendations for an introduction to beets?
