Cheese bun deli has made up (6,4)
I believe the answer is:
danish blue
'cheese' is the definition.
(Danish blue is an example)
'bun deli has made up' is the wordplay.
'made up' indicates an anagram.
'bun'+'deli'+'has'='bundelihas'
'bundelihas' is an anagram of 'DANISH BLUE'.
(Other definitions for danish blue that I've seen before include "served up on board?" , "possibly crackers with it" .)
