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.

Prepare

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

Make the filling

  1. In a bowl, combine the grated lemon rind, lemon juice, melted butter, corn starch, water, and sugar.

  2. Add the egg yolks and mix well.

  3. In a separate bowl, beat the egg whites until stiff peaks form.

  4. Gently fold the beaten egg whites into the lemon mixture.

Bake

  1. Pour the mixture into a pie crust and bake until set.

  2. This recipe makes 3 pies.

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

What each ingredient does

Eggs
Yolks thicken the filling and whites, whipped and folded in, give it a light, airy texture.
Sugar
Sweetens the filling and balances the sharpness of the lemon juice.
Lemon juice
Provides the tart, acidic flavour that defines the pie.
Butter
Adds richness and a smooth, tender texture to the filling.
Corn starch
Thickens the filling so it sets when baked.

The step that matters

Folding the beaten egg whites. Whites must be beaten to stiff peaks and folded in gently; overmixing deflates the foam, and the air it holds is what makes the filling light.

Swap the lemon

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

  1. Vanillafits better
  2. Coconutfits better
  3. Figfits about as well
  4. Lemonthe original

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