Garlicky mayonnaise (5)
I believe the answer is:
aioli
'garlicky mayonnaise' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for aioli that I've seen before include "A lamb joint; driven clouds" , "garlic dip" , "Mayo, in part?" , "11 [SAUCE]" , "Mayonnaise with garlic" .)
