Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Corn starch
Thickens the milk as its starch granules swell and gelatinize when heated.
Milk
Forms the liquid base and, as it heats, provides richness and body to the gruel.

The step that matters

Stir the corn starch mixture into the hot milk. Corn starch clumps if it hits hot liquid unmixed. Pre-mixing it with cold milk separates the granules so they disperse evenly before the starch thickens.

Swap the nutmeg

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

  1. Cinnamonfits better
  2. Nutmegthe original
  3. Gingerfits about as well
  4. Clovefits less well

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