Fancy Easter sun and sweet wine (9)
I believe the answer is:
sauternes
'sweet wine' is the definition.
(I've seen this before)
'fancy easter sun' is the wordplay.
'fancy' is an anagram indicator.
'easter'+'sun'='eastersun'
'eastersun' anagrammed gives 'SAUTERNES'.
'and' acts as a link.
(Other definitions for sauternes that I've seen before include "Sweet white wine" , "A sweet Bordeaux" , "Sweet French wine" .)
