Salad oil holder (5)
I believe the answer is:
cruet
'salad oil holder' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for cruet that I've seen before include "Container for table condiment" , "Small container for seasoning or relish at table" , "Container for condiments" , "Truce over container for table" , "Pepper holder?" .)
