Goose liver pâté (4,4)
I believe the answer is:
foie gras
'goose liver pate' is the definition.

This is the entire clue.
(Other definitions for foie gras that I've seen before include "Edward ---, discovered vaccination" , "Rich food" , "Goose liver paste" , "French delicacy" , "Pate de . . . . . . . . Is made from goose liver" .)
