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 caramel flavor, and helps the filling thicken as it cooks.
Sweet milk
Adds liquid that dissolves the sugar and gives the filling a creamy body.
Butter
Adds fat for smoothness and richness in the finished filling.

The step that matters

Cooking until the mixture thickens. Sugar and milk must be cooked long enough to reach the right concentration. Too little cooking leaves the filling runny and it will not set; stirring gently helps prevent scorching on the bottom of the pan.
