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
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, beat the sugar, butter, and egg yolks together for a long time.
Add the milk and part of the flour, mixing well.
In a separate bowl, combine the remaining flour, cream of tartar, and baking soda.
Gradually add the dry ingredients to the wet mixture, stirring until smooth.
Incorporate the egg whites beaten to stiff peaks gently into the batter.
Bake
Pour the batter into a greased cake pan and bake for 30-40 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 add richness and emulsify the batter; whipped whites lighten the crumb.
- Flour
- Provides the structure that sets the cake's crumb as it bakes.
- Sugar
- Sweetens the cake and helps tenderize the crumb while creaming with butter.
- Butter
- Adds fat for tenderness and flavor, and aids aeration when creamed with sugar.
- Milk
- Adds moisture and hydrates the flour to form the batter structure.
- Cream of tartar
- Stabilizes the whipped egg whites and adds acidity that helps the cake rise.
- Baking soda
- Reacts with acidic ingredients to release gas, helping the cake rise and brown.
The step that matters
Folding in the beaten egg whites. Stiff whites hold air that gives the cake its lift. Mixing them in gently keeps that air from deflating, which would leave a dense cake.
