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

What each ingredient does

Butter
Adds richness and a smooth, glossy mouthfeel to the sauce.
Flour
Thickens the sauce as its starch swells and sets when heated with liquid.
Brown sugar
Adds sweetness, color, and a caramel-like molasses flavor.
Vinegar
Adds acidity that balances the sweetness of the brown sugar.

The step that matters

Stirring the flour in completely. Flour must be fully dispersed into the butter and water while stirring, or it forms lumps that stay raw inside. Starch thickens properly only when evenly distributed in the liquid as it heats to a boil.
