Dressing bottle (5)
I believe the answer is:
cruet
'dressing bottle' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cruet that I've seen before include "it stands on the dinner table" , "Small container for salt or pepper" , "Vinegar bottle" , "Pepper holder?" , "Truce (anag)" .)
