Neaponitan Cake

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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat the oven to 350°F (175°C).

  2. Mix the corn starch and flour together.

Make the batter

  1. In a large bowl, cream the butter and sugar until light and fluffy.

  2. Add the milk and mix well.

  3. Gradually add the flour and corn starch mixture.

  4. Fold in the beaten egg whites gently until combined.

  5. Pour the batter into a greased cake pan.

Bake

  1. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.

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

What each ingredient does

Egg whites
Beaten stiff, they trap air and give the cake its light, airy structure.
Butter
Creamed with sugar, it traps air and adds richness and tenderness to the crumb.
Flour
Provides the main structure that sets as the cake bakes.
Corn starch
Softens the crumb by diluting gluten, giving a finer, more tender texture.
Sugar
Creamed with butter to aerate the batter and adds sweetness and browning.
Cream of tartar
Stabilizes the beaten egg whites so they hold their volume during folding and baking.

The step that matters

Fold in the beaten egg whites gently. Egg whites hold air only when beaten stiff. Overmixing or stirring vigorously knocks out that air, so the cake bakes up dense instead of light.
