Ordering cider as the drink (7)
I believe the answer is:
sidecar
'the drink' is the definition.
(sidecar is a kind of drink)
'ordering cider as' is the wordplay.
'ordering' indicates anagramming the letters.
'cider'+'as'='cideras'
'cideras' anagrammed gives 'SIDECAR'.
(Other definitions for sidecar that I've seen before include "Attachment to motor cycle" , "that biker may take with him" , "Cocktail - cedar is (anag)" , "Is raced (anag.)" , "that's suitable for a non-driver" .)
