In the United States, the term "pigs in a blanket" often refers to hot dogs, or breakfast/link sausages wrapped in biscuit dough, pancake, or croissant dough and baked. The dough is sometimes homemade, but canned dough is most common. They are somewhat similar to a sausage roll or (by extension) a baked corn dog. They are served as an appetizer, a children's dish, or as a breakfast entree. A common variation is to stuff the hot dog or sausage with cheese before wrapping it in dough. At the restaurant chain IHOP, the term "pigs in a blanket" refers to sausage links with pancake wrapped around it.
