Types of Cooking Greens — From Collard Greens to Turnip Greens

Straight-up kale has broad, curly leaves that are a deep green color. Kale is usually cooked a long time or blanched in salted boiling water before being used to tenderize it, reduce its bitterness, and set its beautiful color. The hearty nature of kale helps it stand up to long cooking times, making it a great fit for dishes like Greens With Pepper and Ginger.
