Food said to bring a smile to the face? (6)
I believe the answer is:
cheese
'food' is the definition.
(I know that cheese is a food product)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for cheese that I've seen before include "Edam or cheddar, say" , "Eg, Limburger" , "Gloucester or Gubbeen, say" , "E.g. brie" , "Lancashire, perhaps" .)
