I believe the answer is:
stilton
If this is the answer I cannot explain how the clue works.
Can you help me to learn more?
(Other definitions for stilton that I've seen before include "Cheese variety" , "Cheese named after Cambridgeshire town" , "English blue cheese" , "Type of cheese" , "Dairy product" .)
