Apple 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare the filling

  1. Preheat the oven to 350°F (175°C).

  2. In a bowl, combine the chopped apples, beaten eggs, lemon juice, grated lemon rind, sugar, and salt. Mix well until combined.

Assemble and bake

  1. Place one pie crust in a pie dish and fill it with the apple mixture.

  2. Cover with the second pie crust and seal the edges.

  3. Cut slits in the top crust to allow steam to escape.

  4. Bake for 30-40 minutes or until the crust is golden brown.

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

What each ingredient does

Tart apples
Provide the main body of the pie and tart flavor that balances the sugar.
Eggs
Set the apple filling as it bakes, giving it a sliceable, custard-like body.
Lemon juice
Adds acidity that brightens the sweetness and freshens the apple flavor.
Sugar
Sweetens the filling and helps it brown and develop flavor in the oven.
Lemon rind
Adds concentrated lemon aroma from the aromatic oils in the peel.

The step that matters

Cut slits in the top crust. Slits let steam escape while the filling heats. Without them, trapped steam can build pressure, lift or split the crust, and push filling out.

Swap the apple

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

  1. Orangefits better
  2. Vanillafits better
  3. Limefits better
  4. Applethe original

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