Meat from a calf (4)
I believe the answer is:
veal
'meat from a calf' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for veal that I've seen before include "meat, R [ROSE] maybe" , "Calf flesh" , "Calf's flesh as food" , "what the meat course may be" , "White meat" .)
