Watercress
Description
Watercress is a leafy green aquatic plant belonging to the Brassicaceae family. It is known for its peppery, slightly tangy flavor that adds a zesty kick to various dishes. The lush, small, round leaves and edible stems of watercress are often used fresh in salads, sandwiches, and as a garnish. Watercress thrives in clear, slow-moving water, and its crisp texture makes it a favored ingredient in both raw and lightly cooked preparations.
Common uses
Watercress is commonly used as a fresh, peppery addition to salads, a flavorful garnish, and a nutritious component in smoothies and juices. It also finds its place in hot preparations such as soups, stews, and sautéed dishes, where it contributes a subtle piquancy and vibrant green color. Given its delicate nature, watercress is usually added towards the end of cooking to preserve its texture and nutritional integrity.
