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.
Prepare the batters
Preheat the oven to 350°F (175°C).
In a bowl, beat the egg whites until stiff.
In another bowl, cream the butter and sugar together.
Add the flour, sweet milk, baking powder, and vanilla extract to the butter mixture, mix well, and then fold in the beaten egg whites.
Divide the batter in half and mix one half with the grated chocolate.
Bake
Pour the dark batter into a cake pan, followed by the white batter, and repeat until all batter is used.
Bake for 30-35 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to stiff peaks, they trap air that lifts and gives the cake an airy crumb.
- Butter
- Creamed with sugar to trap air and add richness and a tender texture.
- Sugar
- Creamed with butter to add sweetness and help create a fine, soft crumb.
- Flour
- Forms the cake's structure once baked.
- Baking powder
- Releases gas in the batter, helping the cake rise.
- Chocolate
- Adds flavor and color to one half of the batter, creating the dark layers.
The step that matters
Folding in the beaten egg whites. Stirring rather than folding deflates the whipped whites, losing the air that lightens the cake. Gentle folding keeps the batter light so it rises evenly.
