Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the sauce as it cooks, giving it body and a smooth, pourable texture.
- Sugar
- Adds sweetness and helps balance the bitterness of the chocolate.
- Chocolate
- Provides the main flavor and deep color of the sauce.
The step that matters
Thicken the sauce with flour, stirring continuously. Flour lumps form if it is added without constant stirring, because starch clumps before it disperses. Continuous stirring keeps the starch evenly distributed so the sauce thickens smoothly as it heats.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
