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

What each ingredient does

Sugar
Sweetens the mixture and, once boiled, shapes the filling's firmness as it cools.
Cold water
Dissolves the sugar so it can be boiled into a syrup.
Butter
Adds fat for richness and a smooth, silky mouthfeel.
Shaved chocolate
Provides chocolate flavor and body, thickening the filling as it melts into the hot syrup.

The step that matters

Boil the sugar and water until it threads. Boiling evaporates water and concentrates the sugar, so the stopping point determines how firm the filling becomes as it cools. Stopping too early leaves it soft, while boiling too long makes it hard and grainy.
