Arm broken – can I drink? (7)

I believe the answer is:

martini

'drink?' is the definition.
(martini is a kind of drink)

'arm broken can i' is the wordplay.
'broken' indicates anagramming the letters.
'can' becomes 'tin' (both are metal containers).
'arm' anagrammed gives 'mar'.
'mar'+'tin'+'i'='MARTINI'

(Other definitions for martini that I've seen before include "Type of Italian vermouth" , "Cocktail made with gin or vodka and vermouth" , "alcoholic drink" , "Italian drink" , "Alternative name for Simone Memmi, pre-Renaissance Italian painter" .)

I've seen this clue in The Telegraph.
