Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grated chocolate
- Provides the main flavor and, as it melts and sets, the body of the filling.
- Sugar
- Sweetens the filling and, as it dissolves, helps it thicken and set as it cools.
- Butter
- Adds fat for a smoother, glossier texture and a richer mouthfeel.
The step that matters
Boil until it begins to thicken. Thickening depends on how far the mixture is cooked. Too little heat leaves the filling runny, while overcooking can make it stiff or grainy once it cools. Watch for the first signs of thickening and remove it from heat then.
