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 a smooth, glossy body.
Powdered sugar
Adds sweetness and dissolves easily into the liquid for a smooth sauce.
Lemon juice
Adds acidity and bright lemon flavour that balances the sweetness.

The step that matters

Stir over medium heat until the sauce comes to a boil. Arrowroot must reach a boil to thicken fully. Stirring keeps the starch evenly dispersed so it does not clump or settle on the pan bottom, giving a smooth, glossy sauce.

Swap the nutmeg

How well each one fits the dish's main ingredients (arrowroot, sugar, lemon):

  1. Cinnamonfits better
  2. Turmericfits better
  3. Capersfits better
  4. Nutmegthe original

Fit is the average pairing score against arrowroot, sugar, lemon. Candidates are from the same food group and used in at least 100 recipes.
