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

What each ingredient does

Eggs
Egg yolks thicken the apple filling into a custard as they set in the oven.
Apples
Cooked and pureed apples provide the body and main flavor of the filling.
Egg whites
Whipped whites form a light meringue topping that browns slightly in the oven.
Powdered sugar
Fine sugar dissolves easily into the whipped whites, sweetening the meringue topping.

The step that matters

Baking the custard until set. Egg proteins set at moderate heat and thicken the filling. Under-baking leaves the custard runny, while over-baking can make it weep or turn rubbery.

Swap the apple

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

  1. Blueberryfits better
  2. Figfits better
  3. Orangefits better
