Small table radishes make charming cooked vegetables, softening and mellowing, although they retain some pepperiness. Red ones look cute, but the multicolor Easter Egg bouquet is even more so. Seek out cilantro with its roots intact. Their strong fragrance does not dissipate during cooking, whereas leaves, fragrant as they are, disperse their volatile aromatic oils when heated. Have all ingredients ready and close at hand before you begin cooking, as for any stir-fry dish.
