Variety of mead made with milk (4)
I believe the answer is:
edam
'with milk' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'variety of mead' is the wordplay.
'variety of' indicates an anagram.
'mead' is an anagram of 'EDAM'.
'made' acts as a link.
Can you help me to learn more?
(Other definitions for edam that I've seen before include "town in Holland" , "Yellow cheese with a red covering" , "Red-coated cheese" , "Hard Dutch cheese" , "Cheese made badly" .)
