Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Arrowroot
- Thickens the sauce as it heats, giving it body without cloudiness.
- Chocolate
- Provides the main flavour and colour of the sauce.
- Sugar
- Adds sweetness and helps give the sauce its smooth body.
The step that matters
Boil for five minutes longer, stirring steadily. Arrowroot thickens once it is heated, but it can clump if not stirred. Steady stirring keeps the starch dispersed so the sauce turns smooth and evenly thick.
Swap the arrowroot
How well each one fits the dish's main ingredients (sugar, chocolate, milk, vanilla, cinnamon):
- Sweet potatofits about as well
- Arrowrootthe original
- Capsicumfits less well
- Beetrootfits less well
Fit is the average pairing score against sugar, chocolate, milk, vanilla, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
