Why it works: Milk and butter 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 ↓

Ingredients
Directions
The book says “a moderately quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the sponge
Scald the milk and add the butter to it.
Let the mixture cool until lukewarm.
Add the yeast, salt, sugar, and flour to the mixture and beat continuously for five minutes.
Cover and let rise in a warm place for two hours or until very light.
Add the eggs and bake
Beat the eggs separately until very light.
Add the yolks first, then the whites, stirring carefully.
Let the mixture rise again in a warm place for fifteen minutes.
Pour into a greased Turk's head mold.
Bake at 400°F (200°C) for forty minutes.

Flour and butter 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
- Flour
- Forms the structure that holds the risen crumb once baked.
- Eggs
- Add structure and lightness, especially when whipped and folded in.
- Yeast
- Produces gas during rising, making the batter light and airy.
- Butter
- Adds fat for a tender crumb and richer flavor.
- Milk
- Provides moisture and liquid that hydrates the flour and sets the crumb.
The step that matters
Folding in the beaten eggs. Stirring carefully keeps the air trapped in the whipped eggs. Overmixing deflates the batter, so the second rise and the bake produce a denser, less light crumb.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
