If you've never tried, or even heard of a sausage roll, don't worry - there's still time! Sausage rolls are savory pastries in which sausage (most often pork sausage) is encased in puff pastry. They typically come in one of two sizes - larger snack-sized sausage rolls are typically 4-6 inches long, while smaller appetizer-sized rolls are only 1.5-2 inches. Sausage rolls are common in the UK, Canada, and Australia, and are most often sold in grocery store delis and bakeries. They may be sold frozen in boxes to re-heat at home, where they're commonly served at parties and potlucks.
