Centennial Cake

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 300°F (150°C).

Make the batter

  1. In a large bowl, cream together the butter and powdered sugar.

  2. Add the egg whites and mix well.

  3. Dissolve the baking soda in the sweet milk and add to the mixture.

  4. Sift the cream of tartar through the flour and fold it into the batter gently.

Bake

  1. Pour the batter into round quart tins with straight sides.

  2. Place a slice of citron on top of each cake.

  3. Bake in the preheated oven until done.

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

What each ingredient does

Flour
Provides the structure that holds the cake's crumb together as it bakes.
Butter
Creamed with sugar to trap air and give the cake a tender, rich texture.
Powdered sugar
Creamed with butter for sweetness and a fine, even crumb.
Egg whites
Add structure and help trap air, supporting the cake's rise and set.
Baking soda
Reacts with the acid in the batter to release gas, making the cake rise.
Cream of tartar
Acidic partner to the baking soda, helping produce gas for lift and a lighter crumb.

The step that matters

Fold the cream of tartar through the flour gently. Folding gently keeps the air trapped in the batter. Overmixing develops gluten and deflates the batter, leaving a tougher, denser cake.
