Dutch cheese made round (4)
I believe the answer is:
edam
'dutch cheese' is the definition.
(cheese named after a Dutch town)
'made round' is the wordplay.
'round' says the letters should be written in reverse.
'made' reversed gives 'EDAM'.
(Other definitions for edam that I've seen before include "Made into popular cheese" , "Sphere of Dutch cheese" , "Made into a nice cheese" , "Dutch market town famous for its cheese" , "town in Holland" .)
