Tar with taste (4)

I believe the answer is:

salt

This clue is a double definition.

'tar' is the first definition.
('salt' can be a synonym of 'tar')

'taste' is the second definition.
(salt is a kind of taste)

'with' is the link.

(Other definitions for salt that I've seen before include "Liveliness" , "Common substance" , "Seasoned sailor" , "Pile up" , "Seasoning; old sailor" .)

I've seen this clue in the Evening Standard.
