Pearl 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).

Make the batter

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

  2. Add the milk and mix well.

  3. In another bowl, combine the flour, corn-starch, and baking powder.

  4. Gradually add the dry ingredients to the wet mixture, stirring until smooth.

  5. In a separate bowl, beat the egg whites until stiff peaks form.

  6. Gently fold the egg whites into the batter.

Bake

  1. Pour the batter into a greased cake pan and bake for 30-35 minutes or until a toothpick 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
Whipped to stiff peaks and folded in, they give the cake a light, airy structure.
Butter
Creamed with sugar, it traps air and adds richness and tenderness to the crumb.
Sugar
Creamed with butter, it adds sweetness and helps create a light, fluffy texture.
Flour
Provides the main structure of the cake as it sets in the oven.
Baking powder
Releases gas in the batter, helping the cake rise.

The step that matters

Gently fold the egg whites into the batter. Whipped egg whites hold air that gives the cake its lift. Stirring vigorously knocks out this air and can leave a dense, flat cake, so fold gently with a spatula until just combined.
