Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Semi-sweet chocolate
- Provides the body and rich flavor of the truffle, and sets firm when chilled.
- Butter
- Adds fat that makes the filling smooth and creamy and helps it firm when chilled.
- Powdered sugar
- Sweetens the filling and blends smoothly into the butter for a fine texture.
- Egg yolks
- Add richness and emulsify with the butter for a smooth, creamy mixture.
- Rum
- Adds aroma and flavor characteristic of the truffle.
The step that matters
Soften chocolate gently. Chocolate can seize or scorch if overheated. Keeping the inner pan off the water in a double boiler, or heating gently in short bursts, melts it evenly so it blends smoothly into the butter mixture.
