Amuse-gueules, also known as “amuse-bouches,” are related to hors d’oeuvres, but they are slightly different from an appetizer. Both “bouche” and “gueule” mean “mouth” in French, so “amuse-gueule” and “amuse-bouche” literally mean “food that amuses your mouth.” Traditionally, an amuse-gueule is considered “a gift from the kitchen,” so it’s not ordered from the menu or seen on the bill. It’s usually a one-bite treat, such as a deviled egg, a pastry, caviar, or another delicacy.
