Custard Pies Without Milk

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Preheat the oven to 400°F (200°C).

Make the custard

  1. In a bowl, beat together the eggs, sugar, flour, butter, and salt.

  2. Flavor the mixture to taste.

  3. Add enough boiling water to fill a large pie pan.

Bake

  1. Pour the mixture into a pie crust and bake immediately.

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

What each ingredient does

Eggs
Set the custard into a firm, sliceable structure as they cook.
Sugar
Sweetens the custard and softens its texture slightly.
Flour
Thickens the custard slightly and helps it hold its shape.
Butter
Adds richness and a smooth, tender mouthfeel.

The step that matters

Bake immediately after pouring. Eggs begin to thicken with heat, so a custard left standing before baking can set unevenly. Going straight into the oven helps it cook through into an even, smooth set.
