Pork cut (4)
I believe the answer is:
loin
'pork cut' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for loin that I've seen before include "Cut of meat from between rib and haunch" , "Lumbar region" , "Cut of meat from the lower back and sides" , "Part of body between ribs and hip-bone" , "Part of the back - cut of meat" .)
