Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold boiled fish
- Provides the main body and flavour of the croquettes.
- Flour
- Thickens the milk and butter into a stiff mixture that holds the fish together.
- Milk
- Combines with the flour to form a smooth sauce that binds the fish.
- Egg
- Coats the shaped croquettes so the bread crumbs adhere and help them set when fried.
- Bread crumbs
- Form a crisp, golden crust through browning in hot oil.
The step that matters
Cool the mixture fully before shaping. A warm, loose mixture is too soft to hold its shape and can break apart during dipping and frying. Cooling lets the starch-thickened binder firm up so the croquettes keep their form.
