Chocolate Pie

Oven, in the book's wordsA very moderate oven

Ingredients

Directions

The book says “a very moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Make the filling

  1. Beat the egg yolks until light, then add water.

  2. Mix sugar, flour, chocolate or cocoa, and salt together, then add to the liquid mixture.

  3. Place in a double boiler and cook until thick, stirring constantly.

  4. Remove from heat, then add vanilla and butter.

Fill the shell

  1. Sprinkle 1 teaspoon of flour in the pre-baked pie shell and rub it in gently.

  2. Pour the hot chocolate mixture into the shell.

Top and bake

  1. Make a meringue from the 2 egg whites and spread it on top.

  2. Return the pie to the oven and bake the meringue for 12 minutes at 350°F (175°C).

  3. Sprinkle ½ cup of finely chopped pecans over the chocolate mixture, then add the meringue.

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

What each ingredient does

Eggs
Yolks thicken the filling as it cooks; whites whip into the meringue topping.
Flour
Starch thickens the chocolate filling as it heats.
Chocolate or cocoa
Provides the chocolate flavour and colour of the filling.
Sugar
Sweetens the filling and helps stabilise the meringue.
Butter
Adds richness and a smooth, glossy texture to the filling.

The step that matters

Cooking the filling in the double boiler. Flour starch only thickens fully once the mixture is hot, but it can scorch or form lumps if left unstirred. Constant stirring over gentle heat gives a smooth, evenly thickened custard.

Swap the pecans

The recipe marks pecans as optional. How well each one fits the dish's main ingredients (egg, chocolate, sugar, flour, butter, vanilla):

  1. Almondfits better
  2. Hazelnutfits better
  3. Macadamia nutfits better
  4. Pecansthe original

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