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 to a flaky, moist interior.
Flour
Coats the fish so the surface crisps and browns during frying.
Butter
Adds richness and fat, carrying flavour as the dish is served.
Lemon juice
Adds acidity that brightens the rich butter and fried coating.

The step that matters

Fry until crisp and well browned on both sides. The fish must be thoroughly dry and the fat hot enough so the flour coating browns quickly. Wet fish or cool fat steams the coating, leaving it soggy and pale.
