Lemon Sponge Pie

Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the filling

  1. Preheat the oven to 300°F (150°C).

  2. Cream the butter and sugar together.

  3. Add the flour, salt, lemon juice, and grated rind.

  4. Incorporate the well-beaten yolks of the eggs.

  5. Beat the mixture thoroughly and add the milk.

  6. Fold in the stiffly beaten egg whites.

Bake

  1. Pour into a pie crust and bake for 30 minutes.

Recipe from a historical cookbook (Internet Archive).

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

Eggs
Yolks enrich the custard and whites, folded in stiffly beaten, lighten the filling and help it rise and set.
Butter
Creamed with sugar, it adds richness and a tender texture to the filling.
Sugar
Creamed with butter, it sweetens the filling and balances the lemon's acidity.
Lemon
Juice and grated rind provide tart, aromatic lemon flavour that defines the pie.
Flour
Thickens the filling so it sets into a sliceable custard rather than runny liquid.
Milk
Adds moisture and body, giving the filling a smooth, custardy texture.

The step that matters

Folding in the egg whites. Stiffly beaten whites hold air that lightens the batter. Stirring them too hard or too long deflates the foam, leaving a dense pie instead of a light, sponge-like filling.

Swap the lemon
