Tropical legume cook rarely uses (4)

I believe the answer is:

okra

'tropical legume' is the definition.
(okra is a type of legume)

'cook rarely uses' is the wordplay.
'uses' indicates the answer is hidden within the clue (the answer is used as part of the clue).
'OKRA' is hidden within 'cook rarely'.

(Other definitions for okra that I've seen before include "Pod eaten in soups, stews etc" , "Edible seed pods" , "old ladies' fingers" , "Ladies' fingers with edible pods" , "vegetable soup ingredient" .)

I've seen this clue in The Guardian.
