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 custard as rennet coagulates its proteins into a soft set.
Rennet
Enzyme that causes the warm milk to coagulate into a tender, spoonable curd.

The step that matters

Setting the pan in a cool place. Rennet sets milk best while it stays still and undisturbed. Moving or jarring the pan during setting can break the forming curd and leave the custard grainy or watery.

Swap the nutmeg

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

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

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