Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Dissolves into the syrup that forms the sauce's body and gives it sweetness.
- Chocolate
- Provides the main flavor and, melted into the syrup, gives the sauce its smooth, thick body.
- Cream of tartar
- Adds a little acidity that helps keep the sugar syrup from turning grainy or crystallizing.
- Vanilla
- Adds aroma that rounds out the chocolate flavor.
The step that matters
Remove from heat and stir in vanilla. Vanilla's aromatic compounds are volatile and fade with prolonged heat, so adding it off the heat keeps its fragrance noticeable in the finished sauce.
