Italian parsley is a variety of the parsley plant used as an herb in a wide range of cuisines around the world. The slender stems give way to dark, flat leaves that taste robust and fresh. This herb, also known as flat-leaf parsley, is sold on the stems but only the leaves are most commonly used in cooking, which can be added whole or chopped. Italian parsley has a fresh, clean taste. It is described as slightly peppery, with a hint of citrus, clove, and nutmeg. Adding the fresh herb to a recipe contributes a vibrancy to the dish and helps bring out the flavors of the other ingredients.
