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

What each ingredient does

Chocolate
Provides the main flavor and, as it melts into the liquid, gives the filling body.
Sugar
Sweetens the filling and helps it thicken as the mixture cooks.
Sweet milk
Supplies the liquid that dissolves the sugar and melts the chocolate, and its milk solids help the filling set.

The step that matters

Boiling until it thickens. The filling thickens as its liquid evaporates and the starch and milk solids set. Undercooked, it stays runny; overheated, the sugar and milk solids can scorch on the pan bottom.
