Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Baker’s chocolate
- Provides the chocolate flavour and body of the sauce.
- Arrowroot
- Thickens the sauce as it heats, giving it a smooth, glossy texture.
- Sugar
- Sweetens the sauce and helps give it a syrupy body.
The step that matters
Adding the arrowroot mixture to the boiling liquid. Arrowroot thickens when heated but can clump if added to liquid unevenly. Stirring the mixture in well and keeping the sauce boiling while it is added helps it disperse and thicken smoothly.
Swap the arrowroot
How well each one fits the dish's main ingredients (sugar, chocolate, milk, vanilla):
- Arrowrootthe original
- Sweet potatofits about as well
- Capsicumfits less well
- Potatofits less well
Fit is the average pairing score against sugar, chocolate, milk, vanilla. Candidates are from the same food group and used in at least 100 recipes.
