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. In a bowl, combine lemon juice, grated lemon peel, eggs, sugar, and corn starch.

Prepare the crust

  1. Wet the pie crust first with cold water, then with boiling water to thicken it, but do not make it too thick.

Fill and bake

  1. Pour the mixture into the prepared pie crust.

  2. Bake in a moderate oven at 350°F (175°C) until set, like custards.

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

What each ingredient does

Eggs
Set the filling into a custard-like structure as they coagulate when heated.
Corn starch
Thickens the lemon juice mixture so it holds its shape when sliced.
Lemon juice
Provides sharp acidity that balances the sweetness of the filling.
Sugar
Adds sweetness and helps soften the tartness of the lemon.
Grated lemon peel
Adds concentrated lemon aroma and flavour from the peel's oils.

The step that matters

Bake until set, like custards. Eggs and corn starch thicken the filling as proteins coagulate and starch swells when heated. Underbaking leaves it runny, while overbaking can make the eggs curdle, weep liquid, or crack.

Swap the lemon

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