Broccoflower, also called romanesco, is a yellow-green, decorative cauliflower made of tightly packed, small turrets. Heads are generally smaller and not as dense as cauliflower. If left unharvested, florets will turn white like cauliflower. The crunchy vegetable can be eaten raw or cooked as a side dish with similar preparation to cauliflower or broccoli. It is available year-round from the U.S.
