Fish and chip preparation cooked with lard (8)
I believe the answer is:
pilchard
'fish' is the definition.
(pilchard is a kind of fish)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for pilchard that I've seen before include "Edible herring relative" , "Small sea fish related to the herring" , "Fish of herring family" , "Small marine food fish" , "type of fish" .)
