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.
Make the batter
Cream together the butter and powdered sugar.
Add the beaten yolks of the eggs and mix well.
Dissolve the baking soda in the milk and add it to the mixture.
Stir in the lemon juice and grated peel.
Fold in the beaten egg whites gently.
Sift in the flour gradually, mixing lightly.
Bake and finish
Pour the batter into two long cake pans.
Bake at 350°F (175°C) for 30 minutes.
Ice the cake with 2 to 3 cups of sugar for better flavor.

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, while whipped whites lighten its structure.
- Butter
- Creamed with sugar, it traps air and adds tenderness and richness to the crumb.
- All-purpose flour
- Its proteins set into the cake's structure as the batter bakes.
- Baking soda
- Reacts with the acidity in the batter to produce gas that helps the cake rise.
- Powdered sugar
- Sweetens the cake and, creamed with butter, helps create a fine, tender texture.
The step that matters
Fold in the beaten egg whites gently. Whipped egg whites hold air that gives the cake lift. Overmixing deflates them, leading to a dense, heavy crumb.
Swap the lemon
How well each one fits the dish's main ingredients (butter, sugar, egg, milk, flour):

Fit is the average pairing score against butter, sugar, egg, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
