Also known as Dinosaur kale - lacinato kale is a very hearty cooking green with dark green leaves and lots of earthy, nutty flavor. The leaves are so hearty that even when well cooked they retain a very firm texture. Look for the biggest bunches with the widest leaves you can find. Look at the leaves carefully, you want very dark blue-green leaves with no brown or wilted bits. This kale takes a bit longer to cook than other greens; the upside however is that the leaves hold their shape even under long cooking times, making it great for soups and stews. As with other kale varieties, lacinato is very high in vitamins A and C, as well as iron, manganese, calcium and fiber.
