Swiss dish (6)
I believe the answer is:
fondue
'swiss dish' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for fondue that I've seen before include "Sauce of cheese melted in wine" , "Melted cheese dip" , "Swiss hot cheese dish" , "Dipping sauce" , "Saucy dish" .)
