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 cools.
Egg yolk
Adds richness and helps give the custard a creamy body.
Milk
Forms the liquid base that the arrowroot thickens.
Powdered sugar
Sweetens the custard and dissolves easily in the hot milk.

The step that matters

Pour the boiling milk over the arrowroot paste while stirring continuously. Arrowroot thickens as it is heated in liquid and then sets as it cools. Stirring while adding the hot milk keeps the starch evenly dispersed so it does not clump into lumps.

Swap the arrowroot

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

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

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