Directions

Make the orange mixture

  2. Stir until the sugar dissolves.

  3. Add the yolks of the eggs.

  5. Whisk the egg whites until stiff.

  6. Gently fold the egg whites into the orange mixture.

Bake and fill

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

What each ingredient does

Eggs
Yolks thicken the mixture and whites, whisked and folded in, lighten its texture.
Sugar
Sweetens the filling and helps give it a smooth, set body.
Orange rind
Adds the main orange aroma and flavour to the filling.
Lemon juice
Adds acidity that brightens the sharp orange flavour.
Pastry
Forms a crisp, sturdy shell that holds the filling.

The step that matters

Stir the yolks into the mixture until it just comes to a boil. Egg yolks thicken as they heat, but overheating can curdle them into a grainy texture. Stop heating as soon as the mixture just boils, and keep stirring so it cooks evenly.

Swap the orange

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

  1. Vanillafits about as well
  2. Orangethe original
  3. Figfits about as well
  4. Raspberryfits about as well

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