A saveloy is a type of highly seasoned sausage, usually bright red, normally boiled and frequently available in British fish and chip shops, occasionally also available fried in batter. The word is believed to originate from the Swiss-French cervelas or servelat, ultimately from the Latin cerebrus; originally a pig brain sausage particularly associated with Switzerland.
Although the saveloy was traditionally made from pork brains, the ingredients of a shop-bought sausage are typically pork (58%), water, rusk, pork fat, potato starch, salt, emulsifiers (tetrasodium diphosphate, disodium diphosphate), white pepper, spices, dried sage (sage), preservatives (sodium nitrite, potassium nitrate), and beef collagen casing.
The saveloy is mostly eaten with chips. In The Pickwick Papers (Chapter LV) Solomon Pell, an attorney at the Insolvent Court is described as "regaling himself, business being rather slack, with a cold collation of an Abernethy biscuit and a saveloy".
The saveloy is available in Australia where it is consumed at fairs, fêtes, agricultural shows and sporting events, served on a slice of bread or in a bread roll and liberally covered in tomato sauce. At the turn of the 20th century, the saveloy was described in an Australian court case as a "highly seasoned dry sausage originally made of brains, but now young pork, salted" but by the mid-century it was commonly defined by its size as a 19cm sausage, as opposed to a frankfurter at 26cm. This distinction may be due to the Frankfurter's popularisation (as an ingredient of hot-dogs). Despite "frankfurter" sausage makers being the target of violence in World War I, the story that saveloys were once frankfurters, renamed due to anti-German sentiment is purely apocryphal, as far as Australia is concerned.
Saveloys are popular in New Zealand and Australia, where they are larger than the English type. Beef and chicken varieties are also available. Although they are sold at fish-and-chip shops as in England, they are commonly bought at butchers' shops or supermarkets and cooked by boiling at home. Saveloys are known colloquially as "savs". They are often the basis of the New Zealand battered-sausage-on-a-stick 'hot dog', equivalent to a US corn dog, often sold at fairgrounds and public events. A cocktail sausage is a smaller version of the saveloy, about a quarter of the size, sometimes called a baby sav, a "little boy" or "cheerio". These are a popular children's party food in New Zealand and Australia, often served hot alongside sweet, spicy tomato sauce.
Saveloys are also popular in the North East of England where they are eaten hot in a sandwich with pease pudding. Children also eat them with the skins removed as a soft snack, and they can be bought from most local butchers.
A type of hot dog which is almost indistinguishable from the saveloy is popular in the US state of Maine, where it is commonly known as a "red hot" or "red snapper." It is usually grilled or boiled as is common in the UK. In Australia, saveloys are also known as cheerios.
