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.

Prepare

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

  2. Beat the eggs just enough to blend thoroughly.

Make the custard

  1. Add the sugar, then the flour, and lastly the milk.

  2. Flavor to taste with cinnamon.

Bake

  1. Pour the mixture into a raw pie crust.

  2. Bake until the custard is set.

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

What each ingredient does

Eggs
Set as they heat, giving the custard its structure and body.
Milk
Forms the liquid base that sets with the eggs into a tender custard.
Flour
Thickens the custard so it holds its shape when sliced.
Brown sugar
Adds sweetness and a mild caramel flavor to the custard.

The step that matters

Bake until the custard is set. Egg proteins firm as the custard heats. Underbaked custard stays runny, while overbaking makes it grainy, cracked, or watery as the eggs curdle and weep.

Swap the apple

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

  1. Vanillafits better
  2. Raisinfits better
  3. Figfits better
  4. Applethe original

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