The beautiful leaves of the kale plant provide an earthy flavor and more nutritional value for fewer calories than almost any other food around. Kale is a leafy green vegetable that belongs to the Brassica family, a group of vegetables including cabbage, collards, and Brussels sprouts that have gained recent widespread attention due to their health-promoting, sulfur-containing phytonutrients.
To store, place kale in a plastic storage bag removing as much of the air from the bag as possible. Store in the refrigerator where it will keep for 5 days. The longer it is stored, the more bitter its flavor becomes. Do not wash kale before storing because exposure to water encourages spoilage.
Rinse kale leaves under cold running water. Chop leaf portion into 1/2″ slices and the stems into 1/4 ” lengths for quick and even cooking.
To get the most health benefits from kale, let sit for a minimum of 5 minutes before cooking. Sprinkling with lemon juice before letting them sit can further enhance its beneficial phytonutrient concentration.
