Free bananas came in savoury paste (10)
I believe the answer is:
emancipate
'free' is the definition.
(thesaurus)
'bananas came in savoury paste' is the wordplay.
'bananas' is an anagram indicator (informal term for mad).
'savoury paste' becomes 'pate' (I've seen this before).
'came'+'in'='camein'
'camein' with letters rearranged gives 'emanci'.
'emanci'+'pate'='EMANCIPATE'
(Other definitions for emancipate that I've seen before include "Set free" , "release" , "Liberate" , "setting free" , "Free from slavery" .)
