Orange Pie

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the filling

  1. Preheat the oven to 350°F (175°C).

  2. Grate the rind of 1 orange. Juice 2 oranges.

  3. In a bowl, mix together the sugar and flour. Add the egg yolks and melted butter to the sugar mixture.

  4. Stir in the orange juice and rind.

Bake and top with meringue

  1. Pour the mixture into a pie crust.

  2. Bake until it resembles a finely baked custard.

  3. In a separate bowl, beat the egg whites until soft peaks form. Gradually add 2 tablespoons of sugar to the egg whites.

  4. Spread the meringue on top of the pie.

  5. Return to the oven to brown slightly.

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

What each ingredient does

Eggs
Yolks thicken the filling into a custard, while whites whip into the meringue topping.
Sugar
Sweetens the filling and, in the meringue, stabilizes the whipped egg whites.
Flour
Helps thicken the filling so it sets as a custard rather than running.
Orange juice
Provides the main liquid and bright citrus acidity that flavors the filling.
Butter
Adds richness and a smooth, tender texture to the filling.

The step that matters

Baking the filling until set. Underbaked filling stays runny because egg proteins have not yet coagulated, while overbaking makes the custard grainy and weeping. Bake only until it resembles a finely baked custard, then add the meringue.

Swap the orange

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

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

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