Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Orange Pie

Oven, in the book's wordsA quick oven

Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the filling

  1. Preheat the oven to 400°F (200°C).

  2. Grate the rind of one orange and juice two large oranges.

  3. In a bowl, mix together the sugar and flour, then add the egg yolks and melted butter and stir well.

  4. Pour the mixture into a pie crust.

Bake and top

  1. Bake until it resembles a finely baked custard.

  2. In a separate bowl, beat the egg whites until stiff, then add 2 tablespoons of sugar.

  3. Spread the beaten egg whites over the pie and 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

Egg yolks
Thicken the filling into a custard as they set in the oven.
Egg whites
Beaten with sugar to form a meringue topping that browns lightly in the oven.
Flour
Stabilises the filling so it sets smoothly rather than weeping.
Sugar
Sweetens the filling and helps the beaten whites hold their stiff structure.
Orange juice
Provides the main citrus acidity and flavour of the filling.

The step that matters

Spread the meringue over the pie. Egg whites must be beaten until stiff and spread so they touch the crust edge; otherwise they may shrink or weep during the brief browning in the oven.

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.
