Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Arrowroot
Thickens the boiling water into a smooth, clear, glossy porridge as it gelatinizes.

The step that matters

Mix the arrowroot with cold water until smooth before adding it to the boiling water. Arrowroot starch clumps quickly if it meets hot liquid dry or unmixed. Suspending it in cool water first lets the starch granules disperse evenly, so when they swell in the boiling water the result is smooth rather than lumpy.

Swap the nutmeg

The recipe marks nutmeg as optional. How well each one fits the dish's main ingredients (arrowroot, lemon, sugar):

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

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