Frenchman with ocarina cooked food (8)
I believe the answer is:
macaroni
'food' is the definition.
(macaroni is a kind of food)
'frenchman with ocarina cooked' is the wordplay.
'frenchman' becomes 'm' (abbreviation for Monsieur - like 'Mr').
'with' means one lot of letters go next to another.
'cooked' indicates an anagram.
'ocarina' with letters rearranged gives 'acaroni'.
'm'+'acaroni'='MACARONI'
(Other definitions for macaroni that I've seen before include "Cora and Mina go for pasta" , "Short thick tubes of pasta (8)" , "Omani car (anag)" , "Tubular pasta" , "Type of pasta" .)
