Artist to object to a dish from India (5)
I believe the answer is:
raita
'dish from india' is the definition.
(I've seen this before)
'artist to object to a' is the wordplay.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'to object' becomes 'it' (pronoun for an inanimate object).
'ra'+'it'+'a'='RAITA'
(Other definitions for raita that I've seen before include "Something with yoghurt" , "Curry cooler" , "cooling dish" , "accompaniment to curry" , "yoghurt dish from India" .)
