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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat together the butter, sugar, and egg yolks.
Add the sweet milk and flour, then mix well.
Fold in the beaten egg whites.
Stir in the baking powder thoroughly.
Bake
Pour the mixture into a greased baking dish.
Bake in a moderate oven at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten whites trap air, giving the bread a light, airy crumb.
- Baking powder
- Releases gas in the batter, causing the bread to rise in the oven.
- Flour
- Forms the structure that holds the bread's shape as it bakes.
- Egg yolks
- Add richness and help bind the batter together.
- Butter
- Adds fat for tenderness and a richer flavor.
The step that matters
Fold in the beaten egg whites. Folding gently keeps the air trapped in the whites. Stirring vigorously deflates the batter, which leads to a denser, flatter loaf.
