Kale: leaves and stems need different preparation

Useful to know

In kale, it looks for fresh, dark leaves and more tender stems. Iowa State recommends storing unwashed in the refrigerator and washing before use. If you are buying a ready-packed mixture, check that it is labelled as washed and ready for consumption. [1]

In preparation, look at the leaf and the central stem separately. For fine salad or short processing, you may prefer the leaf portion; for another dish, the recipe may provide for a different use. Don't assume that every relationship has the same tenderness just because it has the same name.

Dry the washed leaves when you mix them with dressing. If the goal is to use the purchase gradually, leave the remaining amount properly stowed, instead of preparing without needing everything at once. The specific label takes precedence over a common kitchen scheme.
