French condiment (5)
I believe the answer is:
aioli
'french condiment' is the definition.
(I know that aioli is a condiment)
This is all the clue.
(Other definitions for aioli that I've seen before include "A lamb joint; driven clouds" , "mayonniase" , "Garlic mayo" , "Pungent sauce" , "11 [SAUCE]" .)
