Cook adores pig feet — a delicacy (4,2,4,4)
I believe the answer is:
pate de foie gras
'delicacy' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'cook adores pig feet a' is the wordplay.
'cook' indicates anagramming the letters.
'adores'+'pig'+'feet'+'a'='adorespigfeeta'
'adorespigfeeta' with letters rearranged gives 'PATE DE FOIE GRAS'.
Can you help me to learn more?
(Other definitions for pate de foie gras that I've seen before include "Goose liver product" , "Savoury food" , "Goose liver paste" .)
