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 together the sugar and butter until light and fluffy.
Add the milk and mix well.
Gradually add the flour, baking powder, and vanilla, mixing until smooth.
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the egg whites into the batter.
Bake and ice
Pour the batter into a greased cake pan and bake for 30-35 minutes.
For the icing, boil the chocolate, sugar, milk, and vanilla until thick.
Let the icing cool, then spread it over the cooled cake.

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 helps the cake rise and become light.
- Flour
- Forms the starch and gluten structure that holds the cake's shape as it bakes.
- Butter
- Creamed with sugar to trap air and add richness and a tender crumb.
- Sugar
- Sweetens the cake and, creamed with butter, helps create a light texture.
- Baking powder
- Releases gas during baking, making the cake rise.
- Chocolate
- Gives the icing its flavor and, once boiled, its thick body.
The step that matters
Folding in the egg whites. Whipped egg whites hold air that gives the cake its lift. Stirring them in vigorously knocks out that air, leaving a dense cake, so fold gently with a spatula until just combined.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
