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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 400°F (200°C).
In a large bowl, combine the flour and salt.
Rub the butter into the flour until the mixture resembles coarse crumbs.
Stir in the baking powder.
In another bowl, beat the egg yolks and mix with the sweet milk.
Add the milk mixture to the flour mixture and stir until just combined.
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the beaten egg whites into the batter.
Bake and serve
Pour the batter into a square pan and bake for 25-30 minutes or until golden brown.
Let cool slightly, then cut into squares for serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the structure that holds the bread together as it bakes.
- Baking powder
- Releases gas in the batter, causing the bread to rise and become light.
- Eggs
- Yolks add richness and set the crumb, while whipped whites add lift and airiness.
- Sweet milk
- Adds moisture and hydrates the flour, helping form a tender crumb.
- Unsalted butter
- Rubbed into the flour to tenderize the crumb and add richness.
The step that matters
Folding in the egg whites. Whipped whites trap air that gives the bread its lift. Stirring them in vigorously knocks out that air, leaving a denser loaf. Fold gently and only until no white streaks remain.
