Broccoli Raab, also called Rapini, has spiked leaves that surround clusters of green buds resembling small heads of broccoli. Small, edible yellow flowers may be blooming among the buds. Although it has broccoli’s name, broccoli raab is not related to broccoli; it’s closely related to turnips. (You’ll notice the leaves resemble turnip greens.) Cook the whole plant—the stems can be removed up to where the leaves begin, and sautéed before adding the leaves to the pan. Broccoli Raab is a source of vitamins A, C, and K, as well as potassium, calcium, and iron.
