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

What each ingredient does

Brown sugar
Provides sweetness and, as it caramelizes, the deep flavor of the sauce.
Cream
Adds fat and richness, giving the sauce a smooth, creamy texture.
Butter
Adds fat for silkiness and a rounded, buttery flavor.
Water
Dissolves the sugar so it can cook evenly without crystallizing.

The step that matters

Boil until the mixture forms a hair-like thread. Sugar syrup changes quickly as its water evaporates and its temperature rises. Stopping at the right point sets the sauce's thickness, and going too far can scorch the sugar and make it bitter.
