A thin variety of sausage, known as the chipolata is often wrapped in bacon and served alongside roast turkey at Christmas time and are known as Pigs in a Blanket or "Pigs in Blankets". They are also served cold at children's parties throughout the year. The word derives from the Italian "cipollata", "onioned" or made with onion, although in this context its literal meaning has been forgotten and it need not contain onion. Black pudding, white pudding and Hog's pudding are fairly similar to their Scottish and European counterparts. Following concerns about health and user preference (distaste for horsemeat), heightened by the BSE crisis in the 1990s and the 2013 horsemeat scandal, the quality of the meat content in many British sausages improved with a return to the artisanal production of high quality traditional recipes, which had previously been in decline. However, many cheaper sausages contain mechanically recovered meat or meat slurry, which must be so listed on packaging.
