Fine veal mince, a must-have for a dolma (4-4)
I believe the answer is:
vine-leaf
'for a dolma' is the definition.
(I've seen this before)
'fine veal mince' is the wordplay.
'mince' indicates anagramming the letters.
'fine'+'veal'='fineveal'
'fineveal' anagrammed gives 'VINE-LEAF'.
'a must-have' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for vine-leaf that I've seen before include "Wrap prevalent in Mediterranean cooking" , "Wrapper used to make dolmades" , "Wrapping of dolmades" .)
