Creme de menthe (French for mint cream) is a sweet, mint-flavored alcoholic beverage. Its flavor is primarily derived from Corsican mint. It is available commercially in a colorless (called "white") and a green version (which obtains its color from the mint leaves or from the addition of coloring, if extract and not the leaves are used to make the liqueur). Both varieties have similar flavors and are interchangeable in recipes, except where the color is important. Creme de menthe is used as an ingredient in several cocktails, such as the Grasshopper and the Stinger, and is also served as an after-dinner drink and can be used in food recipes as a flavoring. The traditional formula involves steeping dried peppermint or Corsican mint leaves in grain alcohol for several weeks (creating a naturally green color), followed by filtration and the addition of sugar. A simple recipe is to mix the creme de menthe with ice cream which creates a mint-like shake. Toppings are also sometimes used, such as nuts or pecans.
