This food holiday celebrates bite-size hot dogs baked in croissant pastry and served, most often, as an appetizer or hors d'oeuvre.

In the United Kingdom, pigs-in-a-blanket refers to small sausages, or chipolatas, wrapped in bacon.

The concept of wrapping meat in dough is ancient and has appeared in various forms worldwide for centuries. In Germany, the dish is called Würstchen im Schlafrock (sausage in a dressing gown); in Mexico, Salchitacos use tortillas; in Finland, nakkipiilo means "hidden sausage"; and in China, Lap Cheong Bao features steamed sausage in pastry.

The first known American printed reference to "pigs in a blanket" appears in Betty Crocker’s 1957 "Cooking for Kids" cookbook.
