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 chocolate and batter
Preheat the oven to 350°F (175°C).
Melt the chocolate, sugar, and milk together in a saucepan.
Cream the butter and sugar together until light and fluffy.
Add the beaten yolks of the eggs to the butter mixture.
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 batter.
Add the vanilla and 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 comes out clean.
For the filling, whip the cream until stiff, sweeten to taste, and flavor with 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
- Yolks enrich the batter and whites, folded in, give the cake lift and a light 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 in the batter so the cake rises and stays light.
- Chocolate
- Gives the cake its chocolate flavor and deep color.
- Milk
- Adds moisture and helps loosen the batter so it bakes evenly.
The step that matters
Folding in the beaten egg whites. Folding gently keeps the air in the whites; stirring hard deflates them, leaving a denser, flatter cake.
