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 molasses flavor, giving the sauce a caramel-like depth.
Butter: Adds richness and body, and firms up as the sauce cools.
Sherry: Adds aromatic flavor and a slight acidity that balances the sweetness.
Molasses: Deepens the flavor and color with a robust, slightly bitter sweetness.
Sugar: Adds sweetness and helps give the sauce a smooth, sweet base.
