Vessel for preparing curries (7)
I believe the answer is:
cruiser
'vessel' is the definition.
(cruiser is a kind of vessel)
'preparing curries' is the wordplay.
'preparing' indicates an anagram.
'curries' anagrammed gives 'CRUISER'.
'for' is the link.
(Other definitions for cruiser that I've seen before include "Large warship" , "Warship; leisure craft" , "Ship" , "A fast warship, sounds leisurely" , "Speedy warship" .)
