Two Crust Lemon Pie

Oven, in the book's wordsA rather hot oven

Ingredients

Directions

The book says “a rather hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Line a pie tin with the bottom crust.

  2. Sprinkle 1 cup of sugar into the crust, then add the grated yellow rind of the lemon.

  3. Peel the white rind from the lemon, slice it thinly, and place it over the sugar.

  4. Sprinkle ½ cup of flour over the lemon slices and add 1 tablespoon of butter.

  5. Pour in 1 cup of cold water and cover with the top crust, sealing the edges tightly.

Bake and serve

  1. Bake in a 400°F (200°C) oven until light brown.

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

What each ingredient does

Sugar
Sweetens the filling and helps balance the sharpness of the lemon.
Lemon
Provides the acidity and aroma that flavour the filling.
Flour
Thickens the liquid filling so it sets rather than running out.
Butter
Adds richness and fat that softens the filling's flavour and texture.
Pie crust
Forms the structure that holds the filling and browns in the oven.

The step that matters

Sealing the top crust. Tight sealing keeps steam and juices inside the pie so the filling cooks through and thickens instead of leaking out during baking.
