Delicacy is mixed with forage (4,4)
I believe the answer is:
foie gras
'delicacy' is the definition.
(I've seen this before)
'is mixed with forage' is the wordplay.
'mixed with' indicates an anagram.
'is' anagrammed with 'forage' can make 'FOIE GRAS'.
(Other definitions for foie gras that I've seen before include "Pate de . . . . . . . . Is made from goose liver" , "Edward ---, discovered vaccination" , "Rich pate" , "Rich food" , "P?t? from goose livers" .)
