Barbecue topping (5)
I believe the answer is:
sauce
'barbecue topping' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sauce that I've seen before include "Cranberry or brandy, say" , "''Hunger is good .....''" , "Food accompaniment" , "sharp language" , "Cheek; condiment" .)
