Tropical nut (6)
I believe the answer is:
cashew
'tropical nut' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cashew that I've seen before include "Chew as you would this nut" , "Acajou" , "Edible nut" , "Kidney-shaped nut of tropical tree" , "Kidney shaped nut" .)
