Also known as kilted soldiers, pigs in blankets is a UK and Irish side dish consisting of cocktail-sized chipolata sausages wrapped in streaky bacon, which can be either pan-fried or baked. Chipolata sausages are fresh, pork-based sausages that are common in the UK.
The first recipes are from 1957, but pigs in blankets did not become popular until the 1990s when Delia Smith, an English cook and TV personality, included a recipe in her cookbook. Today, pigs in blankets are a Christmas staple, usually served as a side dish to roast turkey.
