As cider's drunk, making cocktails (8)
I believe the answer is:
sidecars
'cocktails' is the definition.
(I know this)
'as cider's drunk' is the wordplay.
'drunk' is an anagram indicator.
'as'+'ciders'='asciders'
'asciders' with letters rearranged gives 'SIDECARS'.
'making' acts as a link.
(Other definitions for sidecars that I've seen before include "They're attached to motorbikes to carry passengers" , "cocktails" .)
