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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the milk and egg yolks, mixing well.
In a separate bowl, combine the baking soda, cream of tartar, and flour.
Gradually add the dry ingredients to the wet mixture, stirring until smooth.
Bake
In a clean bowl, beat the reserved egg whites until stiff peaks form.
Gently fold the egg whites into the cake batter.
Pour the batter into two greased loaf pans.
Bake for 30-35 minutes or until a toothpick comes out clean.
Frost and serve
For the frosting, beat the reserved egg whites with grated chocolate, powdered sugar, and vanilla until smooth.
Frost the cake while it is still hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and give a tender, fine crumb.
- Sugar
- Sweetens the cake, helps tenderize the crumb, and aids browning.
- Eggs
- Yolks add richness and moisture, and whipped whites lighten the batter.
- All-purpose flour
- Provides the structure that sets the cake's crumb as it bakes.
- Baking soda
- Reacts with the acid in the batter to produce gas that makes the cake rise.
- Grated chocolate
- Adds chocolate flavor and richness to the frosting.
The step that matters
Gently fold the egg whites into the batter. Whipped egg whites hold air that gives lift. Vigorous stirring knocks that air out, leaving a denser, flatter cake.
