A fillet (or filet) – pronounced /ˈfɪlɪt/ in British English and /fɨˈleɪ/ in American English; from the French word filet, pronounced /filɛ/ – is a cut or slice of boneless meat or fish.
Raw materials:is a cut or slice of boneless meat or fish
Uses:In the case of fish, fillets are generally obtained by slicing parallel to the spine, rather than perpendicular to the spine as is the case with steaks. The remaining bones with the attached flesh is called the "frame", and is often used to make fish stock. As opposed to whole fish or fish steaks, fillets do not contain the fish's backbone; they yield less flesh, but are easier to eat.
