Pearl White 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 the batter

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

  2. Cream together the sugar and butter until light and fluffy.

  3. Add the sweet milk and mix well.

  4. In a separate bowl, beat the egg whites to stiff peaks.

  5. Gradually fold the beaten egg whites into the mixture.

  6. Sift together the corn starch, flour, and baking powder, then fold into the batter.

Bake

  1. Pour the batter into a greased cake pan and bake for 25-30 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, they trap air that lightens the crumb and helps the cake rise.
Butter
Creamed with sugar to trap air and add richness and a tender texture.
Sugar
Creamed with butter to help build a light, fluffy batter and add sweetness.
Flour
Provides the main structure that sets the crumb as the cake bakes.
Baking powder
Releases gas in the batter to help the cake rise.
Corn starch
Softens the crumb by diluting the flour's gluten, giving a finer, more tender texture.

The step that matters

Folding in the beaten egg whites. Egg whites hold air only while stiff. Overmixing or stirring vigorously deflates them, and the cake loses lift and ends up dense. Fold gently and in portions so the air stays in the batter.
