Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

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

Make the filling

  1. In a bowl, mix the lemon rind and juice, butter, chopped apples, egg, and sugar until well combined.

Bake and serve

  1. Pour the mixture into a pie crust and cover with an upper crust.

  2. Bake in the preheated oven until golden brown.

  3. Let cool before serving.

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 tart fruit flavor that forms the pie's filling.
Egg
Helps bind the filling and adds structure as it sets during baking.
Sugar
Adds sweetness and helps the filling brown as it bakes.
Butter
Adds fat for richness and a tender texture in the filling.
Lemon
Its juice and rind add acidity and bright aroma that balance the sweetness.

The step that matters

Let cool before serving. A hot fruit filling is loose and runny because the egg and starches have not yet fully set. Cooling lets the filling firm up so slices hold their shape when cut.

Swap the apple

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

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

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