Crème de menthe
Crème de menthe is used not only as an ingredient for cocktail drinks but as a dessert ingredient or garnish too.
Crème de menthe comes in two colors: green and clear (if you can call “clear” a color). They are both made with corsican mint and they taste the same except that green creme de menthe is made with the leaves (ergo, the green color) while clear creme de menthe is made from the extract. They are often used interchangeably.
