Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk chocolate
- Provides sweet, creamy body and a mild cocoa flavour to the sauce.
- Unsweetened chocolate
- Adds deep chocolate flavour and firm richness that balances the sweetness.
- Caramels
- Melt into the sauce, adding sweetness, smoothness and a buttery caramel note.
- Undiluted evaporated milk
- Adds dairy fat and proteins that make the sauce smooth and thick.
- Strong coffee
- Deepens the chocolate flavour without making the sauce taste of coffee.
The step that matters
Watch the mixture while it cooks. Sugar and milk solids in caramels and chocolate scorch easily when heated for a long time, so the sauce can burn on the bottom and taste bitter. Checking and stirring keeps the heat gentle and the texture smooth.
