A sweet, mild vegetable which deserves to be better known, kohlrabi is especially good in this simple preparation. Choose tennis-ball size or smaller kohlrabis to make sure they are young and tender.
Peel kohlrabis to remove fibrous skin. Slice thinly, or grate coarsely. Add to skillet, stir to coat with butter, and cover. Reduce heat to medium-low and cook until kohlrabi is tender, about 15 minutes for slices, less if grated. Add salt and pepper to taste. Serve hot.
