Broccoli rabe

Rapini or broccoli rabe is a green cruciferous vegetable, with the leaves, buds, and stems all being edible; the buds somewhat resemble broccoli, but do not form a large head. Rapini is known for its bitter taste, and is particularly associated with Mediterranean cuisine. Native to Europe, the plant is a member of the tribe Brassiceae of the Brassicaceae (mustard family). Rapini is classified scientifically as Brassica rapa var. ruvo, or Brassica rapa subsp. sylvestris var. esculenta. It is also known as broccoletti, broccoli raab, broccoli rabe, spring raab, and ruvo kale. Turnip and bok choy are different varieties (or subspecies) of this species. 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. Rapini is a source of vitamins A, C, and K, as well as potassium, calcium, and iron.
