Lemon Sponge 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

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

Make the filling

  1. Cream together the sugar and butter until light and fluffy.

  2. Add the flour, salt, lemon juice, and lemon rind; mix well.

  3. In a separate bowl, beat the egg yolks and add them to the mixture along with the milk.

  4. In another bowl, beat the egg whites until stiff peaks form, then gently fold them into the mixture.

Bake

  1. Pour the filling into a prepared pie crust and bake for about 30‑35 minutes 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 set the custard; whipped whites lighten the filling with air.
Butter
Adds richness and tenderness through fat in the creamed mixture.
Sugar
Sweetens the filling and helps create a light, fluffy texture when creamed.
All-purpose flour
Thickens the filling so it holds its structure while baking.
Whole milk
Adds moisture and liquid for the custard to set around.
Lemon
Provides acidity and aroma from the juice and rind.

The step that matters

Folding in the egg whites. Whites whipped to stiff peaks trap air that gives lift; overmixing or deflating them while folding makes the pie dense and loses that lightness.

Swap the lemon
