Beef cut (4)
I believe the answer is:
loin
'beef cut' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for loin that I've seen before include "Meat between the ribs and rump of an animal" , "Part of body between ribs and hip-bone" , "Cut of meat from between the ribs and rump" , "Part of a carcase" , "Cut of meat from the lower back and sides" .)
