Savoury sauce artist fed to Andalusian beauty? (11)
I believe the answer is:
horseradish
'savoury sauce' is the definition.
'artist fed to andalusian beauty?' is the wordplay.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'fed to' is an insertion indicator.
'andalusian' becomes 'horse'.
'beauty?' becomes 'dish' (slang term for an attractive person).
'horse'+'dish'='horsedish'
'ra' placed within 'horsedish' is 'HORSERADISH'.
(Other definitions for horseradish that I've seen before include "Source of sauce to go with beef" , "Root used in sauce" , "Sauce served with beef" , "Sharp-tasting condiment" , "type of sauce" .)
