Apple Custard

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.

Prepare the filling

  1. Stew the apples until tender.

  2. Run the cooked apples through a sieve.

  3. Add salt, nutmeg, and cinnamon to the apple mixture.

Make the meringue and bake

  1. If meringue is desired, beat the egg whites and gradually add 3 tablespoons of sugar until stiff peaks form.

  2. Pour the apple mixture into a pastry shell and top with meringue.

  3. Bake in a preheated oven at 350°F (175°C) until the meringue is golden.

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 body of the filling, with tartness and fruit flavor.
Egg yolks
Thicken the custard as they set, giving the filling a smooth, rich texture.
Sugar
Adds sweetness and helps stabilize the whipped egg white foam.
Egg whites
Whip into a foam that gives the optional meringue its volume and structure.
Butter
Adds fat for richness and a softer mouthfeel in the filling.

The step that matters

Adding sugar gradually to the egg whites. Adding sugar slowly while whipping lets the foam build a stable structure. Dumping it in all at once, or getting any fat or yolk into the whites, can stop them from reaching stiff peaks.

Swap the apple

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

  3. Lemonfits better
  4. Applethe original

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