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 ↓

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 batter
Preheat the oven to 350°F (175°C).
In a bowl, beat together the butter and sugar until creamy.
Add the egg yolks and mix well.
In a separate bowl, beat the egg whites until stiff peaks form, then fold them into the mixture.
Dissolve the baking soda in the milk and add it to the mixture.
Sift the flour with the cream of tartar and fold it in last.
Bake
Pour the batter into a greased cake pan and 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
- Eggs
- Yolks enrich the batter and whites, whipped to stiff peaks, lighten its structure.
- Butter
- Creamed with sugar, it traps air and adds richness and tender texture.
- White sugar
- Creams with butter to aerate the batter and adds sweetness and browning.
- Flour
- Provides the structure that sets as the cake bakes.
- Baking soda
- Reacts with the acid in the batter to produce gas that helps the cake rise.
- Cream of tartar
- Acidifies the batter, stabilizing the whipped whites and helping the baking soda react.
The step that matters
Folding the whipped egg whites. Whites hold air only when whipped to stiff peaks, and overmixing when folding deflates them, leaving a denser cake. Fold gently and just until combined.
