Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and flavour, and helps form the base roux with the flour.
- Flour
- Thickens the milk into a smooth sauce as it cooks with the melted butter.
- Milk
- Forms the liquid of the sauce, which thickens as the starch in the flour swells.
The step that matters
Adding the milk gradually. Pouring the milk in slowly while stirring keeps the flour evenly dispersed, so the sauce becomes smooth instead of lumpy as the starch swells and thickens.
