Chocolate 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, combine grated chocolate and water. Bring to a boil.

  2. In a bowl, mix egg yolks, cornstarch, and sugar until smooth.

  3. Slowly add the chocolate mixture to the egg mixture, stirring constantly until thick.

  4. Remove from heat and stir in butter until melted.

  5. Pour the filling into the baked pie crust.

Top and bake

  1. Whip the egg whites until stiff peaks form and spread over the filling.

  2. Brown the pie in a 350°F (175°C) oven until the top is golden.

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

What each ingredient does

Grated chocolate
Provides the chocolate flavor and body of the filling.
Egg yolks
Thicken the filling as they set with heat, giving a custard-like body.
Cornstarch
Thickens the filling by swelling in hot liquid, giving it a firm set.
Sugar
Sweetens the filling and helps keep the custard smooth.
Egg whites
Whipped into a meringue topping that browns in the oven.

The step that matters

Stirring the filling as it thickens. Egg yolks can curdle or scramble if they get too hot too fast. Constant stirring while adding the hot chocolate mixture keeps the custard smooth and lets the cornstarch thicken evenly.
