Style of cooking (7)
I believe the answer is:
cuisine
'style of cooking' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for cuisine that I've seen before include "(Regional) style of cooking" , "It can be French, Italian or Spanish in a restaurant and tasty" , "Cooking style characteristic of a place" , "Culinary art" , "French cooking?" .)
