Parsley (Petroselinum crispum) is a bright, grassy-green herb of the carrot family, grown for its fresh, clean, faintly peppery leaves. It comes in two main forms — the frilled, tightly curled type and the broader, flatter "Italian" leaf — and it is one of the most widely used culinary herbs in the world, equally at home as a garnish, a finishing scatter, or the green backbone of dishes like tabbouleh, gremolata and chimichurri.
