Why it works: Milk and butter 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 ↓

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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a large bowl, cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the sweet milk and lemon extract.
In another bowl, combine the flour, baking soda, and cream of tartar.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Bake
Pour the batter into greased cake pans.
Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.

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
- Eggs
- Provide structure and richness as they set during baking.
- Butter
- Adds fat and tenderness, and creaming with sugar traps air for lift.
- Sugar
- Sweetens the cake and helps create a light, fluffy texture when creamed.
- Flour
- Forms the main structure that sets as the cake bakes.
- Baking soda
- Reacts with the acid in the batter to produce gas that makes the cake rise.
- Cream of tartar
- Acidic component that works with baking soda to leaven the batter.
The step that matters
Mixing the dry ingredients into the wet mixture. Overmixing once flour is added develops gluten, which makes the cake tough and dense. Mix only until the flour is just combined so the crumb stays tender.
