Roquefort or Stilton, say (4,6)
I believe the answer is:
blue cheese
I believe this clue is a double definition.
'roquefort' is the first definition.
(I've seen this before)
'stilton say' is the second definition.
(stilton is a kind of blue cheese)
(Other definitions for blue cheese that I've seen before include "Stilton, for instance" , "Dairy product" , "Danish for example" , "Stilton or Roquefort, for example" , "Eg, Stilton" .)
