Lemon Meringue Pie

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the filling

  1. Mix cornstarch and sugar in a bowl.

  2. Add to boiling water, stirring constantly until clear.

  3. Remove from heat and stir in butter, beaten yolks, lemon juice, and lemon rind.

  4. Cool the mixture.

Bake the crust

  1. Line a pie plate with the crust and prick it with a fork.

  2. Bake the crust at 400°F (200°C) until golden.

  3. Fill the baked crust with the lemon mixture.

Make the meringue and bake

  1. In a clean bowl, beat egg whites until soft peaks form.

  2. Add lemon juice, then gradually add sugar, beating until stiff peaks form.

  3. Spread meringue over the lemon filling and bake at 350°F (175°C) until meringue is brown.

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

What each ingredient does

Cornstarch
Thickens the lemon mixture into a sliceable filling as it cooks with the boiling water.
Egg yolks
Enrich and thicken the filling, adding richness and a smooth set.
Egg whites
Whipped into foam to form the airy structure of the meringue topping.
Lemon juice
Adds acidity that gives the filling its bright, tart flavour.
Sugar
Sweetens the filling and, when whipped with the whites, stabilises the meringue.
Butter
Adds fat for a smoother, richer texture in the cooked filling.

The step that matters

Cooking the filling until clear. Starch only thickens fully when it boils while stirred, so stopping early leaves a runny filling, and stirring constantly prevents lumps and scorching on the bottom of the pan.

Swap the lemon

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

  1. Figfits better
  2. Peachfits better
  3. Coconutfits better
  4. Lemonthe original

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