It's made into cheese! (4)
I believe the answer is:
edam
'it's made into cheese' is the definition.
(I've seen this before)
'it's made into cheese' is the wordplay.
'made' can be anagrammed to 'EDAM'.
However, I'm unsure how this is indicated.
Can you help me to learn more?
(Other definitions for edam that I've seen before include "Dutch food" , "Made (anag) - Dutch cheese" , "Spherical cheese" , "Kind of cheese" , "Made into popular cheese" .)
