Ingredients
Directions
The book says “a cool oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Beat the egg whites until stiff peaks form.
Add the powdered sugar and chocolate powder to the egg whites and mix well.
Drop spoonfuls of the mixture onto buttered parchment paper.
Bake
Bake until set.

What each ingredient does
- Egg whites
- Whipped to stiff peaks, they trap air and give the cake its light, airy structure.
- Powdered sugar
- Dissolves into the whipped whites, adding sweetness and helping the mixture hold its shape.
- Chocolate powder
- Adds chocolate flavor and dry bulk that stiffens the foam as it bakes.
The step that matters
Folding in the dry ingredients. Mixing too vigorously after adding the powders deflates the whipped egg whites, which removes the air that gives the cake its lightness and results in a dense texture.
