Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

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

  2. Beat the egg whites until frothy.

Make the batter

  1. Sift together the flour, powdered sugar, and cream of tartar several times.

  2. Slowly add half of the dry mixture to the egg whites.

  3. Stir in the milk and then add the remaining dry mixture, stirring for a few seconds.

  4. Flavor with lemon extract.

Bake

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

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

What each ingredient does

Egg whites
Whipped into foam, they trap air and give the cake its light, airy structure.
All-purpose flour
Provides the starch and gluten that set the cake's structure as it bakes.
Powdered sugar
Sweetens the batter and helps keep the whipped foam fine and tender.
Cream of tartar
Stabilizes the whipped egg whites, helping the foam hold its volume.
Milk
Adds moisture, softening the crumb and loosening the batter.

The step that matters

Folding in the dry mixture. Adding the dry mixture slowly and stirring only briefly keeps the air in the egg white foam. Overmixing knocks out air and gluten develops, leading to a dense, tough cake.
