Prize White Cup 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.

Prepare

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

Make the batter

  1. Beat the egg yolks until light, then add the sugar and mix well.

  2. Add the beaten egg whites alternately with the sifted flour.

  3. Mix the egg whites and flour slowly.

Bake

  1. Pour the batter into a greased cake pan.

  2. Bake until a straw or knife inserted comes out clean.

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

What each ingredient does

Eggs
Yolks enrich and bind the batter, while whipped whites add lift and an airy structure.
Flour
Provides the protein and starch that set into the cake's structure as it bakes.
Butter
Adds fat for a tender crumb and rich flavour.
White sugar
Sweetens the cake and helps keep the crumb tender and moist.
Sour milk
Adds moisture and acidity that reacts with the baking soda.
Baking soda
Reacts with the acid in the sour milk to release gas that helps the cake rise.

The step that matters

Folding in the egg whites with the flour. Beaten egg whites hold air that gives the cake its lift. Mixing them in alternately and slowly keeps that air from deflating, while overmixing develops gluten and can make the crumb tough.
