Lemon Pie

Oven, in the book's wordsA moderately hot oven

Ingredients

Directions

The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the filling

  1. Grate the lemon and beat the egg yolks with the grated rind and juice.

  2. Mix the sugar, butter, and flour thoroughly.

  3. Pour the boiling water over the mixture and dissolve.

Assemble and bake

  1. Add the egg whites beaten to stiff froth and stir into the mixture.

  2. Line a deep pan with pie crust, pour the mixture into it, and bake at 350°F (175°C) until set.

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, beaten to froth, lighten its texture as it sets.
Sugar
Sweetens the filling and balances the sharp acidity of the lemon.
Lemon
Provides the tart flavour and acidity, with its rind adding aroma.
Flour
Helps thicken the filling so it sets rather than running.
Butter
Adds richness and a smooth, tender texture to the filling.

The step that matters

Folding in the beaten egg whites. Whites beaten to stiff froth trap air that lifts the filling. Stirring too vigorously deflates them, leaving a dense, flat pie.

Swap the lemon

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