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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the batters
Preheat the oven to 350°F (175°C).
In a bowl, beat the whites of 4 eggs until stiff.
In another bowl, cream together 1 cup sugar, ½ cup butter, and ½ cup sweet milk.
Add 2 cups flour and 1½ teaspoons baking powder to the mixture and mix well.
Make the dark batter and assemble
For the dark part, beat 1 whole egg and the yolks of 3 eggs with ½ cup butter and 1 cup sugar.
Stir in ½ cup milk, 2 cups flour, grated chocolate, and vanilla.
Layer the light and dark mixtures alternately in a cake pan.
Frost
Make frosting slightly softer than usual and mix in chocolate to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites add lift and a light, airy crumb; yolks add richness and tenderness.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Butter
- Adds fat for a tender texture and rich flavor.
- Sugar
- Sweetens the cake and helps it brown and stay moist.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
The step that matters
Layering the light and dark mixtures. Alternating the batters in the pan lets the two colors and textures bake together into a marbled layer; stiffly beaten whites must be folded gently so the light batter keeps its air.
