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, set custard as it cooks and cools.
Milk
Forms the liquid base that the arrowroot thickens into the blanc-mange.
White sugar
Adds sweetness to the mild, creamy base.

The step that matters

Stir constantly while the mixture thickens. Arrowroot can clump or thicken unevenly if left unstirred over heat. Constant stirring distributes the starch so it gelatinises smoothly and the texture stays even.

Swap the arrowroot

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

  1. Potatofits better
  2. Sweet potatofits about as well
  3. Capsicumfits about as well
  4. Arrowrootthe original

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