Though generally available year round, kale and chard grow well in cool weather and, if protected, may survive in a cold frame over the winter. They can be substituted easily in dishes that call for spinach but have unique tastes in their own right.
Kale (Brassica oleracea) is a member of the cabbage family. The leaves are blue-green in color and almost frilly in appearance. Younger leaves are tender enough to eat raw, but more mature leaves require cooking. Kale is "stemmy," but removing the stems completely does away with most of the leaf, so it is better to chop the leaves and stems well prior to cooking. The leaves should be washed well, especially if harvested from a home garden as kale is very susceptible to aphids. They can then be steamed or sauted, as in the recipe below.
Swiss chard (Beta vulgaris) is a member of the beet family. It is known as a "beetless beet:" the greens without the bulb. The leaves are large and deep green. Chard stems come in various colors depending on variety: white for Fordhook, red for Ruby or Rhubarb and all the colors of a sunset for the Bright Lights Variety. It can be eaten raw in salads or lightly steamed.
