Lemon Sponge Pie

Ingredients

Directions

The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.

Make the filling

  1. Mix flour, sugar, and grated lemon rind in a bowl.

  2. Add beaten egg yolks and milk, then stir until combined.

  3. Gently fold in the beaten egg whites.

Bake

  1. Line a pie plate with crust, pour in the mixture, and bake in a moderate oven (350°F / 175°C) until set.

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

What each ingredient does

Eggs
Egg whites whipped into the mixture add lightness, and the yolks help set the filling.
Flour
Provides structure so the filling holds its shape when baked.
Sugar
Adds sweetness and helps soften the texture of the filling.
Milk
Supplies moisture and liquid that the eggs set into a custard-like filling.
Lemon
Its juice and rind add acidity and aroma to the filling.

The step that matters

Gently fold in the beaten egg whites. Whites hold air that gives the sponge its lift. Stirring vigorously knocks that air out, leaving a denser, flatter pie.
