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

What each ingredient does

Eggs
Egg proteins set as they heat, thickening the custard into a smooth, sliceable texture.
Milk
Forms the liquid base that the egg proteins thicken, giving the custard its body and creaminess.
Sugar
Adds sweetness and softens the set custard slightly, balancing the eggs.

The step that matters

Stir constantly over hot water until it thickens. Egg proteins set gradually as the mixture warms. Constant stirring spreads the heat evenly and keeps the proteins from clumping and curdling against the pitcher, which would leave the custard grainy instead of smooth.

Swap the mace

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

  1. Nutmegfits better
  2. Cardamomfits better
  3. Gingerfits better
  4. Macethe original

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