Kale is a member of the cabbage family and can be tough and bitter. Remove the leaves from the thick stems to blanche and mellow. If you plan on using it raw in salads slice thinly into ribbons. Wash, spin dry and freeze for adding to smoothies. You just crumble off as much as you want and toss in the blender. Kale is one of the best leafy greens for freezing as it gets firm and crunchy when frozen.
