Dish for groom (5)
I believe the answer is:
curry
I believe this is a double definition.
'dish' is the first definition.
(curry is a kind of dish)
'groom' is the second definition.
(synonyms)
'for' acts as a link.
(Other definitions for curry that I've seen before include "Highly spiced dish" , "This powder is a mixture of spices" , "groom" , "Hot spicy dish" , "Dress leather" .)
