Delayed receiving new microwave finally, couple of months back? Hard cheese (8)

I believe the answer is:

emmental

I'm a little stuck... Click here to teach me more about this clue!

'hard cheese' is the definition.
(I've seen this before)

I can't explain the remainder of the clue.

(Other definitions for emmental that I've seen before include "Holy swiss cheese" , "Swiss food" , "Something served on board" , "Cheese for the metal men" , "Variety of cheese" .)

I've seen this clue in The Telegraph.
