Why it works: Apple and lemon are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 7,551 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Apple Custard 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

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

Make the filling

  1. In a bowl, combine the stewed apples, sugar, beaten eggs, butter, and lemon flavoring, and mix well until fully combined.

  2. Pour the mixture into a pie crust.

Bake and serve

  1. Bake for 30-40 minutes or until set.

  2. Let cool before serving.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

Eggs
Coagulate as they bake, giving the custard its set structure.
Stewed apples
Provide moisture, bulk, and the main fruit flavor of the filling.
Sugar
Adds sweetness and balances the tartness of the apples.
Butter
Adds fat for richness and a smoother, softer texture.
Lemon flavoring
Adds a bright citrus aroma that lifts the sweet custard.

The step that matters

Bake until set. Egg proteins coagulate as the filling heats, turning liquid custard firm. Underbaking leaves the pie runny and unsliceable, while overbaking can curdle the eggs and make the custard weep or turn grainy.

Swap the apple

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

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

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