Sweet and sour to be embraced by supporter (6)
I believe the answer is:
toffee
'sweet' is the definition.
(toffee is a kind of sweet)
'sour to be embraced by supporter' is the wordplay.
'sour' becomes 'off' (synonyms).
'to be embraced by' means one lot of letters goes inside another.
'supporter' becomes 'tee' (support for a golf ball in golf).
'off' placed into 'tee' is 'TOFFEE'.
'and' is the link.
(Other definitions for toffee that I've seen before include "Sticky sweet" , "Chewy confection" , "Sugar/butter sweet" , "Chewy confectionery" , "Caramel" .)
