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. Mix the corn starch with a little water.

  3. Pour the boiling water over the corn starch.

  4. Beat the sugar and egg together.

  5. Add the grated lemon and the corn starch mixture to the egg and sugar.

  6. Pour the mixture into a pie crust and bake until set.

Top and brown

  1. Beat the egg white until light and add the powdered sugar.

  2. Spread the meringue on top of the pie and brown in the oven.

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

What each ingredient does

Egg
Yolk thickens and enriches the lemon filling as it sets with heat.
Corn starch
Thickens the filling into a sliceable custard when heated in boiling water.
Lemon
Provides the sharp acidity that balances the sweetness of the filling.
Sugar
Sweetens the filling and counters the lemon's tartness.
Egg white
Whipped into a foam that forms the meringue topping, which browns in the oven.

The step that matters

Pour the mixture into a pie crust and bake until set.. Starch thickens only once it gets hot enough, and the egg must be cooked to set the filling. Underbaking leaves a runny filling that will not hold its shape when sliced.

Swap the lemon
