Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 400°F (200°C).

Make and bake the pie

  1. In a bowl, mix together the chopped apples, beaten egg, sugar, lemon juice, lemon rind, water, and crushed crackers.

  2. Pour the mixture into a pie plate lined with plain pastry.

  3. Cover with a top crust and bake until golden brown.

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

What each ingredient does

Apples
Provide the bulk and fruity flavor of the filling as they soften during baking.
Egg
Binds the filling so it sets rather than running when sliced.
Sugar
Sweetens the filling and helps the apples caramelize slightly for browning.
Lemon
Adds acidity and bright aroma that balance the sweetness of the sugar.
Crushed crackers
Absorb excess juice from the apples so the filling thickens.

The step that matters

Covering with the top crust and baking until golden brown. Baking until golden brown ensures the filling heats through and the starch and egg set, so the slice holds together. Pulling the pie too early can leave a runny filling.

Swap the apple

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

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

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