Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Dissolves into the melted chocolate and sweetens the sauce while thickening it as it cooks.
- Butter
- Adds fat for a smooth, glossy texture and a rounded richness to the sauce.
- Baker's chocolate
- Provides the main chocolate flavour and body of the sauce once melted.
- Boiling water
- Loosens the melted chocolate and sugar into a pourable sauce that thickens as it cooks.
The step that matters
Stirring during the first 5 minutes of cooking. Constant stirring at the start keeps sugar and melted chocolate evenly mixed and prevents them from scorching on the bottom of the pan, which would give a burnt taste and grainy texture.
