Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cold cooked codfish
Forms the main body and flavour of the croquettes.
Thick cream sauce
Binds the flaked fish so the mixture holds its shape.
Egg
Binds the crumb coating so it adheres during frying.
Crumbs
Forms a crisp, browned outer crust when fried.

The step that matters

Let the mixture cool before shaping. A warm, soft mixture will not hold its shape and may fall apart when coated and fried. Cooling lets the cream sauce firm up so the croquettes keep their form.
