Grocer gleefully brought over ingredients for artist (2,5)
I believe the answer is:
el greco
'artist' is the definition.
(I've seen this before)
'grocer gleefully brought over ingredients' is the wordplay.
'ingredients' indicates the answer is hidden within the clue (certain parts or ingredients from the clue).
'brought over' is a reversal indicator.
'ocergle' is hidden within 'grocer gleefully'.
'ocergle' reversed gives 'EL GRECO'.
'for' is the link.
(Other definitions for el greco that I've seen before include "Spanish Renaissance painter" , "Crete-born Sp. painter" , "Cretan-born Spanish painter, d. 1614" , "Sp. painter, born Domen- ikos Theotokopoulos" , "Domenikos Theotokopoulos" .)
