Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Chocolate Cake
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 chocolate mixture
Combine ½ cup sweet milk, 1 cup brown sugar, 1 cup bitter chocolate, and 1 egg yolk in a saucepan.
Boil together and let cool.
Add 1 teaspoon vanilla.
Make and bake the batter
Cream ½ cup butter and 2 egg yolks in a mixing bowl.
Add ½ cup sweet milk and mix well.
Combine 2 cups flour and 1 teaspoon baking soda dissolved in 1 tablespoon vinegar in another bowl.
Mix into the butter mixture.
Add the cooled chocolate mixture to the batter and beat hard for 5 minutes.
Pour batter into a greased cake pan.
Bake at 350°F (175°C) until a toothpick comes out clean.
Make the topping
Boil 1 cup white sugar, 1 cup brown sugar, 1 cup water, and 1 tablespoon vinegar together.
Pour the hot mixture over 2 beaten egg whites.
Fold in a few marshmallows.

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.
