Good capacity for curry (5)
I believe the answer is:
groom
'for curry' is the definition.
(synonyms)
'good capacity' is the wordplay.
'good' becomes 'g' (abbreviation).
'capacity' becomes 'room' (I've seen this before).
'g'+'room'='GROOM'
(Other definitions for groom that I've seen before include "Educate for a future role" , "Horse carer" , "Smarten" , "Attendant for horses" , "man of the match" .)
