Drink as arm worked on trouser material (10)

I believe the answer is:

maraschino

'drink' is the definition.
(maraschino is a kind of drink)

'as arm worked on trouser material' is the wordplay.
'worked' indicates an anagram.
'on' is a charade indicator (letters next to each other).
'trouser material' becomes 'chino' (I've seen this in another clue).
'arm' with letters rearranged gives 'mar'.
'as' after 'mar' is 'maras'.
'maras'+'chino'='MARASCHINO'

(Another definition for maraschino that I've seen is " Harmonicas (anag) - cherry liqueur".)

I've seen this clue in the Sydney Morning Herald.
