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 ↓
Mountain 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
Preheat the oven to 350°F (175°C).
Beat the egg whites and yolks separately.
Make the batter
In a bowl, beat the butter until light, then gradually add the sugar.
Mix in the egg yolks, sweet milk, and lemon extract.
In another bowl, combine the flour, cream of tartar, and baking soda.
Gradually add the dry ingredients to the wet mixture, mixing until smooth.
Fold in the beaten egg whites gently.
Bake
Pour the batter into a greased cake pan and bake for 25-30 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
- Whites trap air for lift, and yolks add richness and structure to the crumb.
- Butter
- Creamed with sugar, it traps air and adds tenderness and flavor.
- Flour
- Its proteins set during baking to form the cake's structure.
- Cream of tartar
- An acid that stabilizes the beaten egg whites and helps them hold their volume.
- Baking soda
- Reacts with acidic ingredients to release gas, helping the cake rise and brown.
- Sugar
- Sweetens the cake, softens the crumb, and helps with browning.
The step that matters
Folding in the beaten egg whites. Stirring vigorously deflates the whites and removes the air that gives the cake its lift. Fold gently, just until no white streaks remain, so the batter stays light and rises evenly.
