Coriander Leaves and Coriander Powder are two popular forms of coriander (Coriandrum sativum), a fragrant herb used in cuisines worldwide for its aromatic and refreshing flavor. While fresh coriander leaves are often used to garnish dishes and add a fresh herbal note, coriander powder is made by grinding dried coriander seeds, providing a deeper, earthy flavor that enhances a variety of cooked dishes.
