Oven, in the book's wordsA moderate oven

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.

Make the batter

  1. Cream the butter and sugar together until light and fluffy.

  2. Mix the grated chocolate, flour, and baking soda into the butter and sugar mixture.

  3. Add the egg yolks one at a time, mixing well after each addition.

Fold and bake

  1. Beat the egg whites until stiff peaks form.

  2. Gently fold the beaten whites into the batter.

  3. Pour the mixture into a pan lined with buttered parchment paper.

  4. Bake in a moderate oven at 350°F (175°C) for 30 minutes.

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

What each ingredient does

Eggs
Egg whites trapped by beating add lift, and yolks add richness and structure to the crumb.
Baking soda
Reacts with the batter to produce gas, helping the cake rise and turn lighter.
Flour
Its proteins set during baking, giving the cake its structure.
Butter
Creamed with sugar to trap air, and adds fat for tenderness and flavour.
Granulated sugar
Creamed with butter to build a light texture and adds sweetness and browning.
Grated chocolate
Provides the chocolate flavour and adds richness to the batter.

The step that matters

Folding in the beaten egg whites. Stirring vigorously deflates the foam trapped in the whites, which is what lifts the cake. Fold gently, so the batter keeps its air and rises evenly in the oven.
