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

What each ingredient does

Light brown sugar
Provides the caramel sweetness and flavor, and thickens as its moisture cooks off.
Milk
Adds moisture and creaminess, and its milk solids help give the filling a soft, smooth texture.
Butter
Adds fat for richness and a smooth, silky mouthfeel.
Vanilla
Adds aroma that rounds out the sweetness of the caramel.

The step that matters

Stirring constantly until the cold-plate test passes. Heating sugar and milk concentrates the mixture and thickens it as water evaporates. Constant stirring keeps it from scorching on the pan base, and the cold-plate test shows when enough moisture has cooked off for the filling to set firmly once cool.
