The radish (Raphanus sativus) is a vegetable of the Cruciferae family. The edible part, a red-skinned bulb of white flesh, is the swollen underground stem just above the root. The bulb is usually eaten raw, but tougher specimens can be steamed. The raw flesh has a crisp texture and a peppery flavour. The "sting" of the taste can be removed by peeling off the red skin. Eating too many radishes can cause one to belch.
