Fried food from back of larder is fish (7)
I believe the answer is:
rissole
'fried food' is the definition.
(I've seen this before)
'back of larder is fish' is the wordplay.
'back of' indicates one should take the final letters.
'fish' becomes 'sole' (sole is a kind of fish).
The last letter of 'larder' is 'r'.
'r'+'is'+'sole'='RISSOLE'
'from' is the link.
(Other definitions for rissole that I've seen before include "Compressed meat and spices in breadcrumbs, fried" , "Spiced meat coated in breadcrumbs and fried" , "Fried ball of minced food" , "Meat product" , "Minced meat or fish deep fried in egg and breadcrumbs" .)
