Self Frosting Lemon Pie

Oven, in the book's wordsA moderate oven

Ingredients

Directions

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

Make the filling

  1. Cream together the sugar, flour, and butter.

  2. Add the beaten yolks, lemon juice, and grated rind, then mix in the milk.

  3. Gently fold in the stiffly beaten egg whites.

Bake

  1. Pour the mixture into a pie plate lined with pastry.

  2. Bake at 350°F (175°C) until golden 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 sourness of the lemon.
Flour
Thickens the filling so it holds its body while baking.
Butter
Adds richness and tenderness to the filling.
Egg yolks
Thicken the filling and add richness as they set in the oven.
Lemon
Provides the sharp acidity and aroma that define the pie.
Milk
Adds liquid and softness, giving the filling a creamy body.
Egg whites
Whipped and folded in, they lighten the filling and help it puff and set.

The step that matters

Folding in the egg whites. Stiffly beaten whites trap air that gives lift. Folding gently keeps that air in, so the filling stays light instead of deflating into a dense layer.

Swap the lemon
