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 ↓
Layer 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
Preheat the oven to 350°F (175°C).
Make the batter
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
In a separate bowl, combine the flour and baking powder.
Gradually add the flour mixture to the butter mixture, alternating with the milk.
Stir in the lemon extract.
Bake and cool
Pour the batter into prepared cake pans and bake until a toothpick inserted in the center comes out clean.
Let the layers cool before frosting or filling as desired.

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
- Creaming with sugar traps air and gives the cake a tender, rich crumb.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Sugar
- Sweetens the cake and helps create a light, fluffy texture when creamed.
- Eggs
- Add structure, moisture and richness, and help bind the batter.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Milk
- Adds moisture and loosens the batter for an even, tender crumb.
The step that matters
Gradually add the flour mixture, alternating with the milk. Adding dry ingredients in portions keeps the batter smooth and emulsified. Overmixing once flour is in develops gluten, which can make the cake tough.
Swap the lemon

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