To clean kale, pull apart the bunch; remove and discard any yellowed or limp leaves. Wash greens in cool water, agitating with your hands. Replace the water two or three times, until there are no traces of dirt. Pat dry with paper towels or use a salad spinner. Place on a cutting board, and cut away tough stems. To remove the hard center fein, fold the leaf in half and eat or cut away.
