Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Forms the main body of the dish, cooking into flaky, tender flesh.
- Flour
- Forms a dry coating that crisps and browns during frying.
- Milk
- Helps the flour adhere to the fish before frying.
- Hot fat
- Cooks the coating quickly, producing a browned, crisp exterior.
- Melted butter
- Adds richness and moisture to the finished dish.
The step that matters
Coating the cod thoroughly with flour. Flour that is patchy or thin will not form an even crust, and bare spots can stick or dry out in the hot fat. An even dry coat, applied just before frying, gives a uniform, crisp surface.
