Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Adds sweetness and helps thicken the mixture as water evaporates during boiling.
- Grated chocolate
- Provides the main chocolate flavor and, as it melts, the body of the mixture.
- Butter
- Adds fat for richness and a smoother, glossier texture.
- Cream or milk
- Supplies liquid and milk fat for a creamy texture and a softer set.
The step that matters
Boiling for 20 minutes while stirring. Long boiling evaporates water and thickens the mixture, so it can over-thicken or scorch on the base of the pan. Stirring spreads heat evenly and keeps sugars and milk solids from burning.
