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

What each ingredient does

Dark sugar
Adds sweetness and a deep caramel flavor to the filling.
Chocolate
Adds richness and body, and deepens the color and flavor.
Milk
Provides liquid that dissolves the sugar and helps the filling thicken when cooked.
Butter
Adds fat for a smooth, rich texture and mouthfeel.

The step that matters

Cooking until it thickens. Over high heat, the milk and sugar can scorch and turn bitter before the mixture thickens. Medium heat and steady stirring let the liquid evaporate gradually, so the filling sets to a spreadable consistency without burning.
