Plain Chocolate Pie

Ingredients

Directions

Make the filling

  1. Dissolve the chocolate in part of the water over low heat.

  2. Add the remaining water, egg yolks, cornstarch, and sugar; whisk together.

  3. Cook on the stove until thickened, then stir in the vanilla.

Bake the crust

  1. Line a pie plate with pie dough and place another pan of the same size inside it.

  2. Bake until the crust is half done, then remove the inner pan and continue baking until fully cooked.

Assemble and brown the meringue

  1. Pour the chocolate filling into the baked crust.

  2. Whip the egg whites until stiff, then add 2 tablespoons of sugar and spread over the filling.

  3. Return to the oven and bake until the meringue is browned.

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 and add richness as they set with the starch.
Cornstarch
Thickens the chocolate filling as it cooks, giving it a firm, sliceable body.
Egg whites
Whip into a stable foam that forms the browned meringue topping.
Grated chocolate
Provides the chocolate flavor and color of the filling.
Sugar
Sweetens the filling and helps stabilize the meringue foam.

The step that matters

Cooking the filling until thickened. Starch needs to reach a boil to fully thicken; undercooked filling stays runny and can soften the crust and meringue once poured in.
