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 as it heats, giving the gruel its body.
Milk
Forms the liquid base and adds creaminess once it is thickened.
Sugar
Adds sweetness to balance the mild milk flavour.
Cinnamon
Adds warm aroma; brandy or raisins can be used instead for flavour.

The step that matters

Stirring the arrowroot into the boiling milk. Arrowroot must be fully dispersed in cold milk before it meets heat, and stirred slowly into the boiling milk, so the starch swells evenly instead of clumping. Constant stirring during simmering keeps it smooth as it thickens.

Swap the arrowroot

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

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

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