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.

Prepare

  1. Grate the rind of the lemon and squeeze the juice.

Make the filling

  1. In a bowl, mix the lemon juice, grated rind, egg yolks, butter, sugar, and milk.

  2. Beat the egg whites until stiff and gently fold them into the mixture.

Bake

  1. Pour the mixture into a pie crust 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
Egg yolks thicken the filling and the whipped whites lighten its texture.
Lemon
Juice and rind provide the sharp acidity and aroma that define the pie.
Sugar
Sweetens the filling and balances the tartness of the lemon.
Milk
Adds moisture and body to the filling, helping it set into a custard.
Butter
Adds fat for richness and a smoother, softer texture in the filling.

The step that matters

Folding the beaten egg whites. Whites must be beaten until stiff and folded in gently. Overmixing deflates the foam, leaving a denser, less airy filling. Under-beating leaves the whites unable to lift the mixture.

Swap the lemon

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