Stew causing an artist complaint? (6)
I believe the answer is:
ragout
'stew' is the definition.
(I know that ragout is a type of stew)
'an artist complaint?' is the wordplay.
'an artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'complaint?' becomes 'gout' (gout is a kind of disease).
'ra'+'gout'='RAGOUT'
'causing' acts as a link.
(Other definitions for ragout that I've seen before include "Highly-seasoned stew" , "Tasty stew" , "Seasoned dish of stewed meat and vegetables" , "Temper showing? No, it's a stew" , "Spicy meat stew" .)
