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, rounded flavour to the sauce.
- All-purpose flour
- Thickens the sauce as it heats, giving it body.
- Brown sugar
- Adds sweetness and a molasses-like depth of flavour.
- Vinegar
- Adds acidity that sharpens and balances the sweetness.
The step that matters
Adding the flour. Flour clumps if dumped in unmixed; stirring continuously while it is dispersed in the liquid lets starch hydrate evenly so the sauce thickens smoothly without lumps.
