Praline nut (5)
I believe the answer is:
pecan
'praline nut' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for pecan that I've seen before include "Species of hickory - edible nut" , "of nuts" , "Nut of American hickory tree" , "Type of nut" , "US nut tree" .)
