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

What each ingredient does

Orange juice
Provides the main citrus flavour and acidity that brightens the custard.
Egg yolks
Set on gentle heat to thicken the custard into a smooth, spoonable texture.
Milk
Adds creaminess and body, softening the sharpness of the orange juice.
Egg whites
Whipped with sugar, they form a light foam that tops the custard.

The step that matters

Thickening over low heat. Egg yolks thicken the custard as they gently set. If the heat is too high or the mixture is left unstirred, the yolks can scramble and turn grainy. Keep the heat low and stir constantly until it coats a spoon.

Swap the orange

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

  1. Vanillafits better
  2. Figfits better
  3. Raisinfits better
  4. Orangethe original

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