Undishable sort of cheese (6,4)
I believe the answer is:
danish blue
'cheese' is the definition.
(Danish blue is an example)
'undishable sort' is the wordplay.
'sort' indicates an anagram.
'undishable' with letters rearranged gives 'DANISH BLUE'.
'of' acts as a link.
(Other definitions for danish blue that I've seen before include "served up on board?" , "possibly crackers with it" .)
