Lemon Cream 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 bowl, beat together the butter and sugar.

  3. Stir the dissolved corn starch into the boiling water.

  4. Add the butter and sugar mixture to the hot water and mix well.

  5. Allow the mixture to cool, then add the lemon juice, lemon rind, and beaten egg yolks.

  6. Pour the mixture into a pie crust and bake without a top crust.

Top and brown

  1. Beat the egg whites until stiff, sweeten to taste, and spread over the baked pie.

  2. Return the pie to the oven and brown the meringue slightly.

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 and a custard-like body.
Corn starch
Thickens the boiling water into a glossy, sliceable filling as it cooks.
Sugar
Sweetens the filling and helps stabilise the beaten egg whites in the meringue.
Lemon juice
Adds acidity that balances the sweetness and gives the filling its bright flavour.
Egg whites
Whip into a foam that sets into a light, airy meringue topping.
Butter
Adds fat for smoothness and a rich mouthfeel in the filling.

The step that matters

Cool the starch mixture before adding the egg yolks. Cornstarch thickens when boiled, and hot egg yolks added too early can scramble and curdle. Letting the mixture cool slightly lets the yolks blend in smoothly and thicken gently in the oven.

Swap the lemon

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