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

What each ingredient does

Eggs
Set the filling into a sliceable custard and add richness and structure.
Sugar
Adds sweetness and balances the tartness of the orange.
Flour
Thickens the filling and helps it hold its shape when cut.
Milk
Adds moisture and softness to the custard.
Orange
Provides acidity and bright citrus aroma from the juice and rind.

The step that matters

Bake until set and lightly golden. Egg proteins coagulate as the filling heats, so it needs enough time to firm up. Underbaking leaves it runny, while overbaking can make the custard curdle, weep, or turn rubbery.

Swap the orange

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

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

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