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 ↓
Velvet 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 batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Dissolve the baking soda in the sweet milk and add to the mixture.
Sift the flour with the cream of tartar and gradually add to the batter.
Flavor with lemon or vanilla.
Bake
Pour the batter into a greased cake pan and bake for one hour.

Flour and butter 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, it traps air and gives the cake a tender, rich texture.
- Sugar
- Creamed with butter, it helps build a light structure and adds sweetness and browning.
- Eggs
- Add structure and richness, setting as the cake bakes.
- Flour
- Forms the main structure of the cake as its proteins set in the oven.
- Baking soda
- Reacts with the acidic cream of tartar and milk to produce gas that makes the cake rise.
- Cream of tartar
- Acts as an acid that reacts with the baking soda to help the cake rise and stay tender.
The step that matters
Creaming the butter and sugar. Beating until light and fluffy works air into the fat, which helps leaven the cake. Under-creaming leaves a dense crumb, while over-mixing after the flour is added can toughen it.
