Cresses are leafy greens commonly used in salads and sandwiches. Synonyms for cresses include watercress, garden cress, upland cress, and land cress. Watercress is a peppery and tangy leafy vegetable that grows in shallow water. Garden cress is a type of fast-growing herb that has a strong aromatic flavor. Upland cress is a bitter and spicy green often used as a garnish. Land cress looks similar to watercress, but it has a milder and sweeter taste. These cresses can add different flavors, textures, and nutrients to your dishes. You can mix and match them to give your salads and sandwiches more variety and complexity.
