Waste battered food (7)
I believe the answer is:
fritter
This clue might be a double definition.
'waste' is the first definition.
(I know that fritter is a kind of the waste)
'battered food' is the second definition.
'fritter' can be an answer for 'food' (a fried food). I'm not certain of the 'battered' bit.
Can you help me to learn more?
(Other definitions for fritter that I've seen before include "Food fried in batter" , "Piece of meat, etc., coated in batter and fried" , "Deep fried item" , "bit of batter" , "Item cooked in batter" .)
