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

What each ingredient does

Light brown sugar
Provides sweetness and body, and helps give the sauce its flavor.
Vinegar
Adds acidity that gives the sauce its sour taste.
Butter
Adds fat and richness, rounding out the sharp flavor.
Flour
Thickens the sauce as it cooks, giving it a smooth body.

The step that matters

Cooking until the sauce thickens. Flour thickens only as its starch heats in liquid. Stirring constantly prevents lumps and scorching on the bottom of the pan, while stopping once the sauce thickens avoids a pasty texture.
