What is "crème de menthe"?

Crème de menthe is a sweet and mint-flavored liqueur that is often used as a flavoring agent in cocktails and mixed drinks. It is made by steeping mint leaves in alcohol, which is then sweetened with sugar or syrup to create a flavorful and aromatic liqueur. Crème de menthe is available in two varieties: green, which is the more common and traditional type, and clear, which is less sweet and has a more subtle mint flavor. It is often used in cocktails such as the Grasshopper and the Stinger, and can also be used to flavor desserts and other sweet dishes. It is known for its refreshing and cooling mint flavor, and is often consumed as a digestif or after-dinner drink.
