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.

Make the filling

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

  2. In a saucepan, combine cold water, egg yolks, flour, white sugar, butter, lemon rind, and lemon juice.

  3. Cook the mixture over medium heat until it thickens into a paste.

  4. Pour the mixture into a pre-baked pie crust.

Top and bake

  1. Beat the egg whites until frothy, then gradually add 2 tablespoons of sugar until stiff peaks form.

  2. Spread the meringue over the pie filling.

  3. Return the pie to the oven and bake until the meringue is light brown.

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

What each ingredient does

Egg yolks
Thicken the filling and add richness as they set with heat.
Flour
Thickens the lemon mixture into a paste as it cooks.
Egg whites
Whip into stiff peaks to form the airy meringue topping.
Lemon juice
Adds the sharp acidity that balances the sweetness of the filling.
White sugar
Sweetens the filling and helps stabilise the whipped meringue.

The step that matters

Cooking the filling until it thickens. The starch in the flour must be cooked fully to swell and thicken the mixture, and the egg yolks must be heated enough to set. Undercooked filling stays runny and can make the pie weep or slump when cut.

Swap the lemon
