A collop is a slice of meat, according to one definition in the Oxford English Dictionary. The derivation is obscure; the OED cites Ihre that it may be related to the old Swedish word kollops (equivalent to the modern: kalops ), but also suggests a German origin (klops).
Scotch collops are a traditional Scottish dish. It can be created using either thin slices or minced meat of either beef, lamb or venison. This is combined with onion, salt, pepper and suet, then stewed, baked or roasted with optional flavourings according to the meat used. It is traditionally served garnished with thin toast and mashed potato.
