The turnip often looks like a large radish, but this varies greatly. Both the root and greens are used.
Turnips are available year round with a peak in the fall and winter months. Select smooth surfaced roots that are firm and heavy with some root hairs at the bottom. In general, the smaller the turnip, the sweeter the taste. Turnips keep well; cut the greens and bag them separately from the root placing them in the crisper section of the refrigerator for up to a week. Turnips can be peeled before cooking, eaten raw, or sliced, diced, or julienned. When cooking this delicate root, cook only to the just tender point; avoid overcooking as sweetness will diminish.
