Tropical sorbet flavor (5)
I believe the answer is:
guava
'tropical sorbet flavor' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for guava that I've seen before include "Yellow-skinned tropical fruit" , "Tropical fruit with yellow skin and pink flesh" , "Fruit from South America" , "Tropical tree with yellow fruit" , "Large cask; tube" .)
