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

What each ingredient does

Egg yolks
Thicken the custard and add richness as they set gently with heat.
Egg whites
Add body and lightness to the custard mixture.
Milk
Forms the liquid base that the eggs thicken into a custard.
Sugar
Adds sweetness to balance the milk and eggs.

The step that matters

Return the mixture to the saucepan and heat while stirring constantly. Egg proteins thicken the custard as it warms, but if the heat is too high or stirring stops, the eggs can scramble and curdle. Gentle, constant stirring keeps the custard smooth.

Swap the lemon

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

  1. Vanillafits better
  2. Lemonthe original
  3. Figfits about as well
  4. Pumpkinfits about as well

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