Cooks fruit in packet, perhaps (9)
I believe the answer is:
steamship
'packet perhaps' is the definition.
(packet boat is a type of steamship)
'cooks fruit' is the wordplay.
'cooks' becomes 'steams' (steaming is a kind of cooking).
'fruit' becomes 'hip' (I have seen 'Fruit of rose ' mean 'hip' so perhaps 'fruit' could also mean 'hip').
'steams'+'hip'='STEAMSHIP'
'in' is the link.
(Other definitions for steamship that I've seen before include "SS in full" , "I pass them (anag) - vessel" , "Queen Elizabeth, for one?" , "Tramp, say" , "Vessel with funnels" .)
