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

What each ingredient does

Arrowroot
Thickens the milk into a smooth custard as it heats.
Egg
Adds structure and richness as it sets the custard.
Milk
Forms the liquid base of the custard.
Sugar
Adds sweetness to the custard.

The step that matters

Scald the mixture. Heating the egg mixture enough to thicken it sets the custard; heating too hard or too long can curdle the egg and leave a grainy texture.

Swap the arrowroot

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

  1. Sweet potatofits better
  2. Capsicumfits better
  3. Asparagusfits better
  4. Arrowrootthe original

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