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, loose gruel as it cooks.
Milk
Forms the liquid base and gives the gruel its body and mild richness.
Sugar
Adds sweetness to balance the plain, starchy base.

The step that matters

Stir the arrowroot paste into the boiling milk. Starch clumps if it hits hot liquid unevenly. Mixing it to a smooth paste first lets the granules disperse, so the gruel thickens evenly without lumps.

Swap the arrowroot

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

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

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