What are "angels of horseback"?

Angels on horseback are a classic appetizer that consists of oysters wrapped in bacon and then broiled or grilled until the bacon is crispy. The dish is believed to have originated in England in the early 20th century and is named for the contrast between the lightness of the oysters and the richness of the bacon. Angels on horseback can be served on their own as a bite-sized appetizer, or as part of a larger seafood platter. They are often paired with a variety of dipping sauces, such as lemon aioli or spicy mayo, to enhance the flavor of the oysters and bacon.
