Chocolate Custard Pie, No. 1

Ingredients

Directions

Make the chocolate base

  1. Dissolve the chocolate in a small amount of milk, then stir it into the boiling water and boil for 3 minutes.

  2. When nearly cold, beat in the yolks of all the eggs and the whites of 3 eggs.

Fill and bake

  1. Stir this mixture into the milk, season, and pour into pie shells lined with puff pastry.

  2. Bake until the custard is set but not more than half done.

Top and finish

  1. Spread the whipped egg whites mixed with 2 tablespoons of sugar over the top.

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

What each ingredient does

Eggs
Egg yolks thicken the custard as it sets, and whipped whites form the light topping.
Milk
Provides the liquid base that the custard sets from, giving it a creamy texture.
Baker's chocolate
Supplies the chocolate flavour and colour of the custard.
White sugar
Sweetens the custard and the meringue-style topping.

The step that matters

Bake until just set. Egg proteins set as they heat, and overbaking squeezes out liquid and makes the custard grainy and watery. Stopping while the centre still trembles lets residual heat finish the set.
