Broccoli Rabe (also known as broccoli raab or rapini) is a green cruciferous vegetable. The edible parts are the leaves, buds, and stems. The buds somewhat resemble broccoli, but do not form a large head. Rapini is known for its slightly bitter taste and is particularly associated with Italian, Galician, and Portuguese cuisines.
The young leaves of these plants as used in cooking are either the same as or the South European equivalent of turnip tops or turnip greens.
Rapini has many spiked leaves that surround clusters of green buds that resemble small heads of broccoli. Small, edible yellow flowers may be blooming among the buds. The flavor of rapini has been described[by whom?] as nutty, bitter, and pungent. The flavour is also reminiscent of mustard greens. Rapini is a source of vitamins A, C, and K, as well as potassium, calcium, and iron.
The cultivated vegetable probably descends from a wild herb related to the turnip that grew either in China or the Mediterranean region. Rapini is similar in shape to the Chinese Brassica oleracea cultivar called kai-lan. Rapini is now grown throughout the world. Rapini is available all year long, but its peak season is fall to spring.
