Chocolate Cake

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the batter

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

  2. Cream together the sugar and butter.

  3. Add the sweet milk, flour, egg, and baking soda, and mix well.

Make the dark part

  1. For the dark part, boil together the sugar, milk, and grated chocolate until thickened.

  2. Remove from heat and stir in the yolk of one egg.

  3. Combine the dark mixture with the light mixture while hot.

Bake

  1. Pour into prepared cake pans and bake until a toothpick comes out clean.

Make the icing

  1. For the icing, boil the sugar and water until it hairs off a spoon.

  2. Stir into the beaten egg white.

  3. Add flavor and beat until nearly cold.

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

What each ingredient does

All-purpose flour
Provides the starch and gluten network that gives the cake its structure.
Egg
Adds structure and richness, helping bind the batter as it sets.
Butter
Adds fat that tenderizes the crumb and carries flavor.
Baking soda
Reacts with the milk to release gas, helping the cake rise.
Sugar
Sweetens the cake and keeps it moist and tender.
Baker's chocolate
Gives the dark part its chocolate flavor and deep color.

The step that matters

Stir the hot syrup into the egg white. Pouring the hot sugar syrup slowly into the beaten egg white cooks and stabilizes the foam. Pouring too fast or letting the syrup cool too much can leave the icing runny or grainy, so beat steadily until it cools.
