Butter 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.

Make the filling

  1. In a saucepan, boil the brown sugar, sweet milk, butter, flour, and egg yolks until thick.

  2. Remove from heat and stir in vanilla to taste.

  3. Fill the two baked pie crusts with the mixture.

Top and bake

  1. Beat the egg whites until stiff, then gradually add the powdered sugar.

  2. Spread the meringue over the filled pies.

  3. Place in a 350°F (175°C) oven to brown.

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

What each ingredient does

Egg yolks
Thicken the filling as they set with heat, giving it a rich, smooth body.
Flour
Thickens the boiled filling so it sets firm enough to slice.
Brown sugar
Adds sweetness and the caramel-like butterscotch flavor.
Egg whites
Whipped into a stiff foam that forms the meringue topping.
Butter
Adds richness and flavor to the filling.

The step that matters

Cooking the filling until thick. Egg yolks and flour thicken only once the mixture is hot enough, but overheating can scramble the yolks. Stir steadily over heat and watch for a thick, smooth texture before removing it from the heat.

Swap the vanilla

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

  1. Vanillathe original
  2. Raisinfits about as well
  3. Figfits less well
  4. Coconutfits less well

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

“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
