Many traditional styles of sausage from Asia and mainland Europe use no bread-based filler and include only meat (lean meat and fat) and flavorings. In the United Kingdom and other countries with English cuisine traditions, many sausages contain a significant proportion of bread and starch-based fillers, which may comprise 30% of ingredients. The filler in many sausages helps them to keep their shape as they are cooked. As the meat contracts in the heat, the filler expands and absorbs moisture and fat from the meat.
