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 bowl, beat the egg whites until very stiff.

  2. Gently fold in the powdered sugar and sifted flour with the cream of tartar. Mix as little as possible to maintain the volume.

Bake

  1. Pour the batter into a prepared cake pan and bake until done.

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

What each ingredient does

Egg whites
Whipped into a stiff foam that gives the cake its light, airy structure.
Powdered sugar
Sweetens the cake and dissolves easily into the whipped whites.
Sifted flour
Provides the set structure that holds the cake's foam once baked.
Cream of tartar
Stabilizes the whipped egg whites so they hold their volume longer.

The step that matters

Folding the batter gently. Egg white foam loses air quickly when overmixed or deflated. Folding gently with a light hand keeps the trapped air that makes the cake rise and stay tender.
