Irish Potato 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 filling

  1. Cream the butter and sugar together until light and fluffy.

  2. Add the egg yolks, nutmeg, mace, and mashed potatoes gradually, beating until very light.

  3. Gently fold in the beaten egg whites.

Bake and serve

  1. Pour the mixture into pie crusts.

  2. Bake until set and lightly golden.

  3. Serve cold.

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

What each ingredient does

Eggs
Egg whites add lift and airiness, while yolks enrich and help set the filling.
Butter
Creaming with sugar traps air, giving the filling a light, tender texture.
Sugar
Sweetens the filling and helps cream the butter into a light, fluffy base.
Mashed potatoes
Provide body and moisture, giving the filling a dense, custard-like texture.

The step that matters

Folding in the egg whites. Egg whites hold air beaten into them. Stirring rather than folding deflates the foam, so the pie bakes up denser and less light.

Swap the mace

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

  1. Cinnamonfits better
  2. Parsleyfits better
  3. Cardamomfits better
  4. Macethe original

Fit is the average pairing score against potato, sugar, butter, egg, lemon, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
