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 the butter and powdered sugar together until light and fluffy.
Beat the egg yolks until thick and light, then add them to the butter mixture.
Alternately add the milk and sifted flour mixed with baking soda, beating thoroughly after each addition.
Fold in the beaten egg whites gently.
Add the grated lemon rind and lemon juice, mixing until combined.
Bake and finish
Pour the batter into a greased cake pan and bake at 350°F (175°C) until a toothpick comes out clean.
Once cooled, cover with icing flavored with lemon juice.

Butter and flour 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
- Butter
- Creamed with sugar to trap air and give the cake a tender, rich crumb.
- Egg yolks
- Add richness, moisture and fat, helping the cake set with a tender texture.
- Egg whites
- Whipped and folded in to add lift and a light, airy structure.
- All-purpose flour
- Provides the main structure that sets as the cake bakes.
- Baking soda
- Reacts with the acidic lemon juice to produce gas that helps the cake rise.
- Milk
- Adds moisture and softens the batter so the flour hydrates evenly.
The step that matters
Folding in the egg whites. Whipped egg whites hold air that gives the cake its lift. Stirring them vigorously deflates the foam, so fold gently with a spatula until just combined.
Swap the lemon

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.
