Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. 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. 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
Preheat the oven to 350°F (175°C).
Beat the egg whites until stiff peaks form.
Cream the butter in a large bowl.
Make the batter
Add the sugar and egg yolks to the butter, beating until very light.
Gradually add the flour and beaten egg whites alternately, mixing well.
Pour the batter into a greased loaf pan.
Bake
Bake for about 1 hour or until a toothpick inserted in the center comes out clean.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Unsalted butter
- Creams with sugar to trap air, giving the cake a tender, rich crumb.
- Granulated sugar
- Creams with butter to create air pockets and adds sweetness and browning.
- All-purpose flour
- Provides the structure that holds the cake together as it bakes.
- Eggs
- Yolks add richness and emulsify the batter; whipped whites lighten its texture.
The step that matters
Folding in the egg whites. Adding the flour and whipped whites alternately, and mixing gently, keeps the batter light. Overmixing after the flour goes in develops gluten and makes the cake dense and tough.
