Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce and carries flavor, giving it a rich mouthfeel.
- Flour
- Thickens the melted butter and milk into a smooth, stable sauce.
- Sweet milk
- Forms the liquid base that the flour thickens as it cooks.
- Mayonnaise
- Adds emulsified fat and tang, giving the finished sauce a creamy texture.
The step that matters
Cook until thick, stirring constantly. Flour thickens only when heated, and stirring keeps starch granules dispersed so they do not clump or scorch on the bottom of the pan. Gentle double-boiler heat prevents the sauce from boiling hard and breaking.
