what is a parmesan rind

A Parmesan rind is the outer, protective layer that develops on the outside of a wheel of Parmigiano-Reggiano cheese as it ages. While it is edible, it can become too hard and tough to chew. However, it is a versatile ingredient that can be used to add flavor to soups, stews, broths, and sauces. Parmesan rinds can be added to the pot during the last 30 minutes or so of cooking to extract all the flavor. They can also be used to flavor risottos, beans, and other dishes. According to Chef Lees, Parmesan rinds truly shine when used to deepen the flavors of stocks, broths, and sauces. If you dont want to use the rind immediately, you can store it in the freezer and use it later.
