Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- The main protein, which cooks through in the hot fat to a flaky, tender texture.
- Milk
- Acts as a binding layer so the flour coating adheres evenly to the fish.
- Flour
- Forms a coating that browns and crisps in the hot fat, giving a crunchy outer layer.
- Hot fat
- Cooks the coating quickly, producing a golden, crisp crust while keeping the fish moist.
The step that matters
Fry in plenty of hot fat. Enough hot fat keeps its temperature when the cold fish goes in. The flour coating sets and crisps quickly, sealing in moisture. Fat that is too cool soaks into the coating, leaving it greasy and soggy.
