Is scared to shake cocktails (8)

I believe the answer is:

sidecars

'cocktails' is the definition.
(I know this)

'is scared to shake' is the wordplay.
'to shake' is an anagram indicator.
'is'+'scared'='isscared'
'isscared' anagrammed gives 'SIDECARS'.

(Other definitions for sidecars that I've seen before include "They're attached to motorbikes to carry passengers" , "cocktails" .)

I've seen this clue in The Irish Independent.
