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 ↓
California 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).
In a large bowl, cream together the sugar and butter.
Add the milk and eggs, mixing well.
In a separate bowl, combine the baking powder and flour.
Gradually add the dry ingredients to the wet mixture, stirring until smooth.
Add flavoring or dried fruit if desired.
Bake
Pour the batter into greased bread tins.
Bake until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Eggs
- Add structure and richness, and help bind the batter.
- Butter
- Adds fat for tenderness and flavor, and helps trap air when creamed with sugar.
- Sugar
- Sweetens the cake and helps browning, and aerates the batter when creamed with butter.
- Baking powder
- Releases gas during baking, making the cake rise and become light.
- Milk
- Adds moisture and helps form the batter's liquid base.
The step that matters
Gradually add the dry ingredients to the wet mixture. Adding flour in portions and stirring just until smooth keeps the batter evenly mixed and limits gluten development, which helps prevent a tough or lumpy cake.
