Tronchuda kale, also known as Portuguese kale, is a traditional Portuguese leafy green recognized for its large, broad, flat leaves and thick white ribs. Its tender, mildly sweet leaves are perfect for soups, stews, and sautéed dishes. The thick stems are also edible and can be peeled and enjoyed raw or cooked, much like celery. Tronchuda kale is a key ingredient in the traditional Portuguese Kale Soup.
