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 molasses-like caramel flavor and color of the filling.
Sweet cream
Adds fat and moisture, giving the filling a smooth, rich body.
Butter
Adds fat for richness and a smoother texture as the filling sets.
Vanilla
Adds aroma that rounds out the sweet, caramel flavor.

The step that matters

Boiling to the thickening point. Boiling drives off water and concentrates the sugar, so the mixture thickens as it cools. Stop too early and the filling stays runny; cook too far and it can turn hard or grainy.
