Scotch 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 the pie

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

  2. Slice the apples and place them in a pie pan. Add the water to the apples.

  3. In a bowl, mix the flour, baking powder or baking soda, and shortening until stiff enough to spread over the apples. Spread the mixture over the apples.

Make the sauce

  1. In a saucepan, combine the tablespoon of flour, butter, sugar, and nutmeg. Stir in a little cold water. Pour in the boiling water.

  2. Boil for five minutes or until the sauce is clear.

Serve

  1. Serve the pie with the sauce poured over it, either cold or warmed.

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

What each ingredient does

Tart apples
Provide the fruit filling, with tartness that balances the sweet sauce.
All-purpose flour
Forms the stiff topping that spreads over the apples and bakes into a crust.
Baking powder or baking soda
Leavens the topping so it rises and becomes light rather than dense.
Shortening
Adds fat that tenderizes the topping and keeps it crumbly.
Sugar
Sweetens the sauce and helps it thicken and turn glossy.
Flour (for sauce)
Thickens the sauce as it boils with the butter and sugar.

The step that matters

Boil the sauce until clear. Flour needs to boil to fully thicken and lose its raw starchy taste. Stopping early leaves the sauce cloudy and thin.

Swap the apple

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

  1. Raisinfits better
  2. Vanillafits better

  4. Applethe original

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