Whipped dish (6)
I believe the answer is:
mousse
'whipped dish' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for mousse that I've seen before include "Creamy dessert; hair dressing" , "Fluffy dessert - cosmetic for hair" , "Frothy creamy substance for styling hair" , "Creamy substance used for styling hair" , "Foamy dish" .)
