White Mountain 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. In a bowl, mix the butter and sugar until creamy.

  2. Add the cornstarch and mix well.

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

  4. Gradually add the flour and cream of tartar, mixing until smooth.

  5. Fold in the egg whites gently.

Bake

  1. Pour the batter into four square cake tins.

  2. Bake until golden and 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 whites trap air that lifts the cake and gives it an airy structure.
Flour
Provides the main structure that holds the cake together as it sets.
Butter
Adds fat that tenderizes the crumb and carries flavor.
Cornstarch
Softens the flour's gluten, giving a finer, more tender crumb.
Cream of tartar
Acid that stabilizes the egg whites and reacts with baking soda to help rising.
Baking soda
Reacts with the acid in the batter to release gas that helps the cake rise.

The step that matters

Fold in the egg whites gently. Egg whites hold air that makes the cake light. Stirring vigorously knocks that air out, so the cake bakes up dense and heavy instead of airy.
