Potted meat is a form of traditional food preservation in which hot cooked meat is placed in a pot, tightly packed to exclude air, and then covered with hot fat.[1][2] As the fat cools, it hardens and forms an airtight seal, preventing some spoilage by airborne bacteria.[3]
Before the days of refrigeration, potted meat was developed as a way to preserve meat when a freshly slaughtered animal could not be fully eaten immediately.[3][4]
Spores of Clostridium botulinum can survive cooking at 100 °C (212 °F),[5] and, in the anaerobic neutral pH storage environment, result in botulism.
Often when making potted meat, the meat of only one animal was used,[3][2] although other recipes, such as the Flemishpotjevleesch, used three or four different meats (animals).
