Kale

Kale is a member of the cabbage family. It is available in decorative and edible versions and is known for its distinctive ruffled leaves.  The two most common edible versions are curly kale and black kale.  See listings for each type.  The picture shown includes black kale (top) and curly kale (bottom).  Both are highly nutritious with kale being on the list of today's "super foods".  This green is easily found in most grocery stores as well as in your local farmer's market. 

My favorite is the black kale.  I simply steam it, drain it well, then saute it with a little olive oil and garlic.

Substitutes For Cavalo Nero

You can substitute different varieties of Kale such as curly or Tuscan Kale which can be used interchangeably.  Otherwise here are some alternatives:
OR>Collard greens - easy to find but take longer to cook
OR>Chinese kale (gai lan) - may be harder to find, cooks quickly
OR>Green chard - easy to find and  cooking time is about the same
OR>Mustard greens- a more peppery flavor
OR>Spinach - cooks very fast, softer, mild flavor.

1 lb. kale = 6 cups raw leaves or 1 1/4 cups cooked leaves
1 cup chopped, raw kale leaves = 2 1/3 ounces (67 grams)
