Chocolate Custard 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 custard

  1. Scald the sweet milk and mix in the grated chocolate until dissolved.

  2. In a bowl, combine the egg yolks, whole egg, vanilla extract, and sugar. Stir in the chocolate mixture.

Make the crust and frosting

  1. For the frosting, beat the egg whites until soft peaks form, then gradually add 4 tablespoons of sugar until stiff peaks form.

  2. For the crust, mix the flour, lard, 1 egg white, 2 teaspoons sugar, water, and a pinch of salt until a dough forms.

Assemble and bake

  1. Roll out the dough and fit it into a pie pan. Pour the chocolate custard filling into the crust.

  2. Top with the egg white frosting and bake at 350°F (175°C) until set.

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

What each ingredient does

Eggs
Yolks and whites thicken the custard and set the frosting, giving structure.
Sweet milk
Forms the liquid base of the custard, setting as it bakes.
Grated chocolate
Provides the chocolate flavor and color throughout the custard.
Sugar
Sweetens the custard and stiffens the egg white frosting.
All-purpose flour
Forms the structure of the pastry dough for the crust.
Lard
Adds fat to the crust, making it tender and flaky.

The step that matters

Bake at 350°F until set. Egg-thickened custard sets as proteins coagulate with heat. Underbaking leaves it runny, while overbaking can make it weep or crack, so watch for a firm set at the centre.
