Lemon Meringue 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. Grate 1 lemon and add the juice of another lemon.

  2. Beat the yolks of 3 eggs and sweeten to taste.

  3. Stir in 2 cups of milk with 2 tablespoons of flour dissolved in it until smooth. Add the milk mixture to the lemon, stirring continuously until mixed.

Bake the pie

  1. Dust a little flour over the bottom of the pie crust, pour in the mixture, and bake at 350°F (175°C) until set. Remove from the oven and cool for a few minutes.

Make and add the meringue

  1. Beat the whites of 3 eggs to a stiff froth, then add 3 tablespoons of powdered sugar and beat together. Spread the meringue over the top of the lemon filling and bake quickly at 400°F (200°C) until 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 the milk.
Flour
Thickens the milk mixture so the filling holds its shape when sliced.
Egg whites
Whipped into a stiff foam that forms the meringue topping.
Lemon juice
Provides the sharp acidity that balances the sweetness of the filling.
Milk
Forms the body of the custard filling with the egg yolks.

The step that matters

Baking the meringue quickly. Meringue sugar and whites can weep or shrink if baked too long, while brief high heat sets and browns the surface before the filling and foam deflate.

Swap the lemon

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