Romanesco is a vegetable in the brassicas family, which includes other cruciferous plants such as cabbage, kale, and brussels sprouts. It has a chartreuse color, pointy florets that look like miniature Christmas trees, firm texture, and lightly earthy flavor. Although sometimes known as romanesco cauliflower, it is a separate variety of vegetable and actually tastes more like broccoli (mild, nutty, and a little sweet). Like both broccoli and cauliflower, it holds up to a variety of different cooking methods, including roasting, sauteing, stir fry, and more.
