Tastier sort of singer (7)
I believe the answer is:
artiste
'singer' is the definition.
(thesaurus)
'tastier sort' is the wordplay.
'sort' is an anagram indicator.
'tastier' anagrammed gives 'ARTISTE'.
'of' acts as a link.
(Other definitions for artiste that I've seen before include "One entertaining" , "A sitter for a performer" , "Theatre performer" , "'Public performer, dancer or singer (7)'" , "Attires for professional entertainer" .)
