Swiss or American
I believe the answer is:
cheese
'swiss or american' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for cheese that I've seen before include "Milk product like gorgonzola" , "Product of milk curds" , "Food made from milk curds" , "Caerphilly" , "Produce created from milk curds" .)
