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 ↓
Lemon 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 cake batter
Preheat the oven to 350°F (175°C).
Beat the egg whites and yolks separately.
Cream the butter and 1 ½ cups sugar together until light and fluffy.
Add the egg yolks, milk, baking powder, and flour to the mixture, and mix well.
Fold in the beaten egg whites gently.
Bake and make the frosting
Pour the batter into prepared cake pans and bake until golden.
For the frosting, combine 1 cup sugar, 2 tablespoons butter, 2 eggs, and lemon juice in a saucepan.
Boil the mixture until it reaches the consistency of jelly, stirring constantly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites add lift when beaten and folded in; yolks add richness and structure to the crumb.
- Butter
- Creaming with sugar traps air, giving the cake a light, tender texture and rich flavor.
- Sugar
- Sweetens the cake and helps hold air when creamed with butter, supporting a soft crumb.
- Flour
- Provides the structure that sets the cake as it bakes.
- Baking powder
- Releases gas in the batter, causing the cake to rise in the oven.
- Lemon juice
- Adds bright acidity and lemon flavor to the frosting.
The step that matters
Folding in the beaten egg whites. Stirring vigorously deflates the whites and loses the air that lifts the cake. Folding gently keeps the batter light so it rises well.
Swap the lemon
