Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Provides sweetness and the caramel flavour as it cooks and thickens.
- Butter
- Adds fat for richness and a smooth, glossy texture in the sauce.
- Milk
- Adds liquid and moisture, helping the sugar dissolve and the sauce loosen.
- Grated chocolate
- Adds deeper flavour and a slightly bitter note that complements the sweetness.
The step that matters
Boil the mixture for 20 minutes, stirring occasionally. Sugar can scorch or crystallise on the base of the pan if left unattended. Regular stirring keeps heat even, and the sauce thickens as water evaporates and the sugar caramelises.
