Romanesco is one of the most far out and edible flowers. It is a cruciferous vegetable that belongs to the Brassica family that was originated in Italy. Superficially, it is a fractal of buds structurally similar to cauliflower but with a green hue.
When eaten raw it is crunchy, but the texture can be altered by sautéing, roasting, or to retain the most nutrients, steaming them to your liking. The taste, however, is much like cauliflower but considerably lighter and more nutty. It is commonly eaten alongside meat, starches, and even in salads.
