Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White sugar
- Adds sweetness and body to the sauce as it dissolves and thickens.
- Brown sugar
- Adds sweetness and a deeper, caramel-like flavour to the sauce.
- Milk
- Provides the liquid that the sugars dissolve into and cook down to form the sauce.
- Chocolate
- Supplies the chocolate flavour and helps give the sauce its richness.
- Butter
- Adds fat for smoothness and a rich mouthfeel in the finished sauce.
- Nut meats
- Add crunchy texture and a toasted, nutty flavour to the sauce.
The step that matters
Cooking until the mixture granulates at the edge. Sugar and milk must cook down far enough to thicken, but not so far that the sugar crystallises. Overcooking makes the sauce grainy or hard as it cools, while undercooking leaves it thin and runny.
