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 ↓

Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Cream the butter and sugar together.
Thoroughly beat the egg yolks to a very stiff froth.
Make the batter
Add the sour milk and mix well.
Gradually add the flour and baking powder, mixing until smooth.
Flavor to taste.
Bake
Bake in a slow oven at 300°F (150°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Provide richness and structure, and their beaten froth lightens the batter.
- Butter
- Adds fat for tenderness and a rich flavor.
- Sugar
- Sweetens the cake and helps it brown as it bakes.
- Sour milk
- Adds moisture and acidity that reacts with the baking powder.
- Flour
- Forms the structure that holds the cake together as it sets.
- Baking powder
- Releases gas that makes the cake rise.
The step that matters
Beating the egg yolks to a very stiff froth. Air whipped into the yolks gives the batter its lift. If the yolks are under-beaten, the cake will be dense, and mixing too vigorously after the flour is added can toughen it.
