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

What each ingredient does

Sugar
Sweetens the filling and, when boiled, thickens into a syrupy caramel base.
Sweet chocolate
Adds chocolate flavor and body to the filling as it melts into the syrup.
Butter
Adds fat for a smoother, richer texture and mouthfeel.

The step that matters

Boiling until ropy. Sugar syrup must reach the right concentration to thicken. Stop too early and the filling stays runny; cook too long and it can harden or scorch. Ropy syrup forms long threads when a spoon lifts it, signaling readiness.
