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

What each ingredient does

Arrowroot
Starch that thickens the hot milk into a smooth, glossy body as it heats.
Milk
Liquid base that gives the pudding its creamy body once thickened.
Lemon
Adds bright acidity and aroma that balances the sweetness.
Sugar
Adds sweetness to the pudding.

The step that matters

Stirring while the milk thickens. Arrowroot starch can clump if it meets hot liquid unevenly, and it thickens quickly once heated. Stirring continuously spreads the starch evenly so the pudding sets smooth rather than lumpy.

Swap the arrowroot

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

  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, lemon, sugar. Candidates are from the same food group and used in at least 100 recipes.
