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 milk into a smooth, set custard-like texture.
Milk
Forms the body of the blancmange and provides creaminess and moisture.
Sugar
Adds sweetness and balances the mild flavor of the milk.

The step that matters

Stir the arrowroot paste into the boiling milk, then keep stirring while adding sugar and vanilla. Starch granules swell and thicken only when heated while moving, so stirring prevents lumps and scorching on the bottom of the pan. Arrowroot thickens quickly and can turn thin if overcooked or held at a rolling boil too long.

Swap the arrowroot

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

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

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