Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Clay 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 batter
Preheat the oven to 350°F (175°C).
In a bowl, cream the butter and sugar until it resembles whipped cream.
In a separate bowl, beat the egg yolks until well combined.
In another bowl, beat the egg whites until stiff peaks form.
Add the beaten yolks and flour to the creamed mixture, mixing well.
Gently fold in the beaten egg whites.
Bake and finish
Pour the batter into two cake pans and bake until golden brown.
For variety, change the flavoring or add fruit to one cake.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich and bind the batter, while whipped whites add lift and a light, airy crumb.
- Butter
- Creamed with sugar, it traps air and adds richness and a tender texture.
- Sugar
- Creaming with butter aerates the batter and sweetens the cake while helping it brown.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking soda
- Reacts with the acid in the batter to produce gas that helps the cake rise.
- Cream of tartar
- Stabilizes the whipped egg whites so they hold their peaks longer.
The step that matters
Gently fold in the beaten egg whites. Whipped egg whites hold the air that lifts the cake. Vigorous stirring deflates them, leaving a dense, flat cake.
