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 ↓
Feathered Cake
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Mix the batter
Cream the butter and sugar together.
Add the egg and milk, mixing well.
Sift the baking powder into the flour and combine with the wet ingredients.
Bake
Pour the batter into a prepared baking pan.
Bake in a 400°F (200°C) oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Adds sweetness and helps the crust brown during baking.
- Butter
- Adds fat that makes the crumb tender and rich.
- Egg
- Binds the batter and adds structure as it sets.
- Milk
- Adds moisture and helps form a soft, tender crumb.
- Flour
- Provides the main structure that holds the cake together.
- Baking powder
- Releases gas in the batter, causing it to rise.
The step that matters
Combining the flour with the wet ingredients. Mixing only until the flour is just combined keeps gluten development low, so the cake stays tender. Overmixing makes it tough, and baking powder loses lift if the batter sits too long before baking.
