Buttermilk 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).

Make the custard

  1. In a bowl, mix the flour, eggs, butter, sugar, and buttermilk until well combined.

  2. Pour the mixture into two pie crusts.

Bake

  1. Bake in the preheated oven until set and lightly browned.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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 the filling its structure.
Flour
Thickens the custard so it holds its shape when sliced.
Butter
Adds richness and fat, softening the texture of the filling.
Sugar
Sweetens the filling and contributes to lightly browning the top.
Buttermilk
Adds moisture and a tangy acidity that balances the sweetness.

The step that matters

Bake until set and lightly browned. Eggs keep setting as they cool, so underbaking leaves a runny center while overbaking can make the custard curdle, weep, or crack. Check for a set center that still jiggles slightly in the middle.
