A zingy unicorn
If you walk through a market and see something resembling a unicorn's horn, it may be a daikon. Also known as a white radish, this Asian root vegetable has quite a zing to it. Look for bunches sold with the leaves, which should be dark green and not wilted. You can steam or stir-fry the greens, but cut them off the roots right away to keep the daikon crisp. Shred or slice the root and make a quick pickle with vinegar, sugar and salt, or use it in stir-fries and soups. Daikon is rich in vitamin C, potassium and fiber.
