Kale is the most ancient and among the earliest cultivated member of the cabbage family. It was a favorite vegetable in ancient Rome and has remained a particularly popular vegetable in Scotland and Ireland. Nutritionally, kale is vastly superior to most vegetables. It is very rich in vitamins A and C, and calcium. B vitamins and other minerals are also in excellent supply. Kale also has the highest protein content of all of the cultivated vegetables.
- Wrap kale in damp towel or place in plastic bag and keep in the hydrator drawer of the refrigerator.
- Kale is best used fresh but will keep for 2-4 days if kept moist and refrigerated.
