Cheese to gorge? (7)
I believe the answer is:
cheddar
This clue is a double definition.
'cheese' is the first definition.
(cheddar is a kind of cheese)
'gorge?' is the second definition.
(Cheddar Gorge in Somerset)
'to' is the link.
(Other definitions for cheddar that I've seen before include "Mendip gorge" , "Hard 8 across" , "Firm cheese as made in Somerset" , "Hard cheese" , "Popular cheese originally from Somerset" .)
