Common turnips are made up of edible roots, stems and leaves. Several stems of the plant sprout from the bulbous root into broad green leaves. The root itself is roughly 3 inches in diameter, two-toned with magenta blushed tops and white bottoms that flow into the bulb’s tapered thin taproot. Often, the taproot is trimmed before being sold in a supermarket. Turnips have a similar flavor and texture to radishes. Their bone white flesh is firm, crunchy succulent, earthy sweet and peppery.
