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 medium oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a saucepan, melt the chocolate, 3 tablespoons sugar, and 2 tablespoons milk together.
Cream the butter and sugar together until light and fluffy.
Add the beaten egg yolks to the butter mixture, then stir in the melted chocolate mixture.
Sift the flour with the Magic Baking Powder five times, then add it alternately with the milk to the mixture until fully combined.
Stir in the vanilla and then gently fold in the beaten egg whites.
Bake and assemble
Pour the batter into a greased loaf pan or divide it into three layers.
Bake in the preheated oven until a toothpick inserted comes out clean.
For the filling, whip the cream until stiff, sweeten to taste, and add the coffee extract.
Layer the cake with chopped walnuts and whipped cream between the layers and on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg whites are folded in to add lift and a light, airy crumb.
- Butter
- Creamed with sugar, it traps air and gives the cake a tender, rich texture.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Magic baking powder
- Releases gas during baking so the cake rises and becomes light.
- Chocolate
- Adds the main chocolate flavor and deep color to the batter.
- Heavy cream
- Whipped to stiffness, it forms a moist, creamy filling between the layers.
The step that matters
Folding in the beaten egg whites. Egg whites hold air that gives the cake its lift. Stirring them vigorously deflates the foam, leaving a dense cake, so fold gently until just combined.
