Lemon Pie

Oven, in the book's wordsA cool oven

Ingredients

Directions

The book says “a cool oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Make the filling

  1. In a saucepan, boil the sugar, water, and butter together.

  2. Mix the corn starch with a little water and add it to the boiling mixture.

  3. Beat the egg yolks and stir them in along with the lemon juice.

Bake and serve

  1. Bake the pie crust first until golden.

  2. Pour the filling into the crust when it is slightly cool.

  3. Bake in a cool oven at 300°F (150°C) until set.

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 as they set and add richness to the custard.
Corn starch
Thickens the boiling liquid into a smooth, glossy filling.
Lemon juice
Adds the sharp acidity that gives the filling its tang.
Sugar
Sweetens the filling and balances the lemon's acidity.
Butter
Adds fat for a rich, smooth texture in the filling.

The step that matters

Pour the filling into the crust when it is slightly cool.. A filling poured in while very hot can soften the baked crust and make the pie soggy. Letting it cool slightly keeps the base crisp and helps the filling set evenly.

Swap the lemon

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