Potato Pies

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 filling

  1. In a bowl, combine the mashed potatoes, beaten eggs, milk, lemon juice, lemon rind, brandy, and butter. Mix until smooth to form a thin batter.

  2. Prepare a pie crust and fill it with the potato mixture.

Bake

  1. Bake until golden brown, about 30-40 minutes.

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

What each ingredient does

Mashed potatoes
Provide the bulk and body of the filling.
Eggs
Set during baking to give the filling structure and richness.
Butter
Adds fat for richness and a smooth, tender texture.
Lemon
Adds acidity and aroma that brighten the sweet filling.
Brandy
Adds aroma and flavour to the filling.

The step that matters

Mix until smooth to form a thin batter. Lumps of potato or unevenly beaten egg stay visible after baking. Mixing until smooth gives the filling an even texture, and the eggs blend in better when beaten separately first.

Swap the lemon
