Apple-custard Tart

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

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

Make the custard

  1. In a bowl, combine the apple sauce, beaten eggs, and fresh milk.

  2. Add vanilla flavoring if desired.

  3. Pour the mixture into a pie crust-lined dish.

  4. Sprinkle ground cinnamon on top.

Bake

  1. Cut strips of the remaining crust and lay them across the top.

  2. Bake in the preheated oven until set.

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

What each ingredient does

Eggs
Set the custard as they cook, giving it a firm, sliceable texture.
Apple sauce
Provides apple flavor and moisture, and sweetness to the custard.
Fresh milk
Adds liquid and richness that help the custard become smooth and tender.
Pie crust
Forms the base and edge that hold the custard while it bakes.

The step that matters

Bake until set. Eggs thicken as their proteins coagulate with heat. Pulling the tart too early leaves a runny custard, while overbaking can make it dry, grainy, or cracked.

Swap the vanilla

The recipe marks vanilla as optional. How well each one fits the dish's main ingredients (apple, sauce, egg, milk, cinnamon):

  1. Vanillathe original
  2. Pearfits about as well
  3. Figfits less well
  4. Plumfits less well

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