It's Halloween, so what better time to examine this root vegetable that looks like it would grow in Tim Burton's vegetable garden? They resemble shrunken heads or mud-covered baseballs, but these are actually black radishes.
Although they're a common sight for Eastern Europeans and the French, you'd be forgiven if you thought they were just dirty turnips. Beneath their dark exteriors appears to be a rather pale and innocent interior that can be a trick or a treat depending on your taste inclinations. They pack the same peppery punch as their red cousins but with the sharp, nose-tickling heat of horseradish.
Try them sliced and roasted in olive oil and salt for a milder bite or grated raw over a salad for a piquant counterpoint. Because black radishes are dryer and denser than other radishes, they're perfect for pickling too.
