Syrup from claret produced around east (7)
I believe the answer is:
treacle
'syrup' is the definition.
(I know that treacle is a type of syrup)
'claret produced around east' is the wordplay.
'produced' indicates an anagram.
'around' means one lot of letters goes inside another.
'east' becomes 'E' (synonyms).
'claret' anagrammed gives 'tracle'.
'tracle' enclosing 'e' is 'TREACLE'.
'from' acts as a link.
(Other definitions for treacle that I've seen before include "Thick syrup from sugar cane" , "cloying stuff" , "Sticky produce" , "refined product" , "Syrup-like substance" .)
