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 the deep caramel flavour as it cooks.
Milk
Supplies liquid and milk solids that thicken and brown during cooking.
Butter
Adds fat for richness and a smoother, softer texture.
Vanilla extract
Adds aroma that rounds out the caramel flavour.

The step that matters

Cook until thick. The mixture thickens as water evaporates and the sugars and milk solids concentrate. Heat that is too high can scorch the sugars and milk solids, giving a burnt taste or a grainy texture, so the gentle water bath helps control it.
