Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that cooks with the flour to form a roux, adding richness to the sauce.
- Flour
- Starch that thickens the milk into a smooth white sauce that holds the mixture together.
- Milk
- Liquid that, heated with the roux, forms the body of the thick white sauce.
- Egg
- Binder that helps the croquette mixture hold its shape while frying.
- Meat or fish
- Main filling that gives the croquettes their substance and flavor.
The step that matters
Slowly pour in the cold milk, stirring until the mixture thickens. Adding cold milk gradually while stirring lets the flour starch disperse evenly before it swells as the mixture heats, which prevents lumps and gives a smooth sauce.
