Neapolitan Custard Pudding

Oven, in the book's wordsA moderate oven

Ingredients

Directions

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

Prepare the base

  1. Spread a little jam over each slice of sponge cake.

  2. Place the slices in a buttered pie dish.

  3. Sprinkle powdered biscuits and a little bitter almond flavor over the cake.

Make the custard

  1. In a saucepan, sweeten the milk with sugar rubbed on the lemon rind and heat until nearly boiling.

  2. Mix flour with a little cold water and stir into the hot milk.

  3. Add butter and stir until the mixture thickens.

  4. Let it cool slightly, then add the beaten yolks of the eggs.

  5. Pour the custard over the sponge cake in the pie dish.

Bake and finish

  1. Bake in a moderate oven (350°F / 175°C) until it stiffens.

  2. Whip the egg whites to a firm froth and spread on top of the pudding.

  3. Sift powdered sugar over the surface.

  4. Return to the oven for 8-10 minutes before serving.

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

What each ingredient does

Eggs
Yolks thicken the custard and whites whip into a light topping that sets in the oven.
Sponge cake
Forms the soft base that soaks up the custard as the pudding bakes.
Milk
Forms the liquid base of the custard, which thickens and sets as it bakes.
Flour
Thickens the hot milk into a stable custard that holds its shape.
Butter
Adds richness and a smooth, tender texture to the custard.
Sugar
Sweetens the milk and the topping, and helps the egg whites hold a froth.

The step that matters

Adding the egg yolks to the custard. If the custard is too hot when the beaten yolks go in, the eggs can scramble and turn grainy. Letting it cool slightly first keeps the custard smooth and lets it set evenly in the oven.
