Lemon 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 the filling

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

  2. In a bowl, mix the sugar, egg yolks, water, and cornstarch or flour until smooth.

  3. Add the lemon juice and grated rind, and stir well.

  4. Pour the mixture into a pie crust.

Top and bake

  1. Beat the egg white until stiff peaks form and spread it over the filling.

  2. Bake for about 25 minutes or until the meringue is golden.

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 rich, creamy custard as they set.
Egg white
Whipped into stiff peaks to form the airy, golden meringue topping.
Cornstarch or flour
Thickens the lemon mixture so it holds its shape when sliced.
Lemon
Provides the tart, bright acidity that balances the sweetness.
Sugar
Sweetens the filling and helps stabilise the meringue.

The step that matters

Beat the egg white until stiff peaks form. Under-beaten white stays loose and weeps, while the sugar and whipped structure hold air that bakes into a stable meringue. Spread it fully over the filling so it seals to the crust edge.

Swap the lemon

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

  4. Figfits about as well

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