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.

  1. Combine ½ cup sweet milk, 1 cup brown sugar, 1 cup bitter chocolate, and 1 egg yolk in a saucepan.

  2. Boil together and let cool.

  3. Add 1 teaspoon vanilla.

Make and bake the batter

  1. Cream ½ cup butter and 2 egg yolks in a mixing bowl.

  2. Add ½ cup sweet milk and mix well.

  3. Combine 2 cups flour and 1 teaspoon baking soda dissolved in 1 tablespoon vinegar in another bowl.

  4. Mix into the butter mixture.

  5. Add the cooled chocolate mixture to the batter and beat hard for 5 minutes.

  6. Pour batter into a greased cake pan.

  7. Bake at 350°F (175°C) until 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

Flour
Provides the structure that holds the cake's crumb together as it bakes.
Butter
Adds fat for a tender texture and rich flavor in the crumb.
Bitter chocolate
Supplies the chocolate flavor and deep color of the cake.
Baking soda
Reacts with the vinegar to produce gas that lifts and aerates the batter.
Egg whites
Whipped into the hot sugar syrup to form a light, stable marshmallow-style topping.
Brown sugar
Adds sweetness and moisture, and contributes a molasses flavor.

The step that matters

Pour the hot sugar syrup over the beaten egg whites. The syrup must be hot and poured in a thin stream while beating so it cooks the egg white proteins and forms a stable, glossy foam instead of a runny or grainy one.
