Fried food recipe is fish (7)
I believe the answer is:
rissole
'fried food' is the definition.
(I've seen this before)
'recipe is fish' is the wordplay.
'recipe' becomes 'r' (abbreviation in medical prescriptions).
'fish' becomes 'sole' (sole is a kind of fish).
'r'+'is'+'sole'='RISSOLE'
(Other definitions for rissole that I've seen before include "Croquette" , "Fried and breadcrumbed dish" , "Fried meat dish" , "Losers I find in the chopped meat dish" , "Compressed meat and spices in breadcrumbs, fried" .)
