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

What each ingredient does

Milk
Forms the body of the dessert, setting into a soft curd when rennet is added.
Rennet
An enzyme that curdles the milk, causing it to set into a firm, tender custard.
Egg yolk
Adds richness and fat, giving the set custard a smoother, creamier texture.
Sugar
Provides sweetness and balances the mild flavor of the milk.

The step that matters

Cool the milk until only lukewarm before adding the rennet. Rennet is an enzyme that works best at about body temperature. If the milk is still hot, the enzyme can be destroyed, and the mixture will fail to set properly.

Swap the nutmeg

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

  1. Cinnamonfits better
  2. Nutmegthe original
  3. Gingerfits less well
  4. Allspicefits less well

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