Polish drink served up with salt (9)
I believe the answer is:
elaborate
'polish' is the definition.
(I've seen this before)
'drink served up with salt' is the wordplay.
'drink' becomes 'ale' (type of beer).
'served up' says the letters should be written backwards (in a down clue, going upwards).
'with' is a charade indicator (letters next to each other).
'salt' becomes 'borate' (borate is a kind of salt).
'ale' backwards is 'ela'.
'ela'+'borate'='ELABORATE'
(Other definitions for elaborate that I've seen before include "Complicated - work out" , "Ostentatious, possibly" , "Give more details" , "Complicated, with many parts or details" , "Extravagant" .)
