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 caramel flavour as it cooks with the milk and butter.
Butter
Adds fat for a rich, smooth texture in the finished filling.
Milk
Provides liquid that cooks down with the sugar to form the caramel base.

The step that matters

Boil while stirring constantly. Sugar and milk can scorch on the bottom of the pan if left unstirred, giving a burnt taste. Constant stirring keeps heat even so the mixture thickens smoothly.
