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

What each ingredient does

Brown sugar
Adds sweetness and a molasses flavour that deepens the sauce.
Butter
Adds richness and a smooth, glossy mouthfeel.
Vinegar
Adds sharp acidity that balances the sweetness.
Flour
Thickens the sauce as its starch swells in the hot liquid.

The step that matters

Gradually add the boiling water while stirring thoroughly. Adding hot liquid slowly while stirring keeps the sugar and other dry ingredients dispersed, so the sauce stays smooth instead of forming lumps.
