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 ↓
White 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.
Make the cake
Preheat the oven to 350°F (175°C).
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the flour, sweet milk, lemon juice, and grated lemon rind, mixing well.
In a separate bowl, beat the egg whites until stiff peaks form.
In another bowl, combine the baking soda and cream of tartar, then add to the batter.
Gently fold in the beaten egg whites.
Pour the batter into jelly cake pans and bake until a toothpick comes out clean.
Make the icing and assemble
For the icing, boil the water and sugar until thick.
Pour the hot syrup over the beaten egg whites and beat until cool.
Layer the cake with icing and dredge with flour before icing.

Flour and butter 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
- All-purpose flour
- Provides the structure that holds the cake's crumb together as it bakes.
- Unsalted butter
- Creams with sugar to trap air and gives the cake a tender, rich texture.
- Eggs
- Whites are whipped to add lift and light texture, while the yolks add richness and structure.
- Granulated sugar
- Adds sweetness and, creamed with butter, helps create a light, fine crumb.
- Baking soda
- Reacts with the acid in the batter to produce gas that makes the cake rise.
- Cream of tartar
- Acidifies the batter and stabilizes whipped egg whites, helping them hold their volume.
The step that matters
Gently fold in the beaten egg whites. Whipped egg whites trap air that gives the cake its lift. Stirring or mixing vigorously knocks that air out, so the cake bakes up denser and flatter. Fold slowly with a spatula until just combined.
