Exquisite soup mixed with rice (8)
I believe the answer is:
precious
'exquisite' is the definition.
(thesaurus)
'soup mixed with rice' is the wordplay.
'mixed with' is an anagram indicator.
'soup' mixed up with 'rice' makes 'PRECIOUS'.
(Other definitions for precious that I've seen before include "Valuable or dearly beloved" , "as good as gold" , "Having great value" , "Valuable, treasured" , "Very fastidious" .)
