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

What each ingredient does

Arrowroot
Thickens the milk as its starch swells when heated, giving a smooth, glossy texture.
Milk
Forms the liquid base and adds body and richness to the porridge.

The step that matters

Cook until the mixture thickens, then remove from heat. Arrowroot starch swells and thickens as it heats, but overheating or cooking too long can break down the starch so the porridge turns thin. Removing it from heat as soon as it thickens keeps the texture smooth.

Swap the arrowroot

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

  1. Arrowrootthe original
  2. Sweet potatofits about as well
  3. Capsicumfits less well
  4. Asparagusfits less well

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