Sour-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

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

  2. Beat the egg whites and yolks separately.

Make the filling

  1. Dissolve the corn starch in a little water, then cook it in boiling water until thickened.

  2. Combine the cooked corn starch with the brown sugar, butter, and orange juice.

  3. Fold in the beaten egg yolks, then gently fold in the egg whites.

Bake

  1. Pour the mixture into a pie shell and bake until set.

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

What each ingredient does

Eggs
Yolks enrich and thicken the filling, while whipped whites lighten its texture.
Corn starch
Gelatinizes when cooked in hot water, thickening the filling so it sets.
Brown sugar
Adds sweetness and moisture while balancing the acidity of the orange juice.
Orange juice
Provides the sour citrus acidity and flavor that defines the pie.
Butter
Adds richness and a smooth, tender mouthfeel to the filling.

The step that matters

Folding in the egg whites. Whites hold air from beating, which lightens the filling. Folding gently preserves that air; stirring vigorously deflates the whites and leaves a denser pie.

Swap the orange

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

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

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