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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Heat the milk and butter together until lukewarm.
Combine the lukewarm milk and butter with the flour in a large bowl.
Add the yeast, eggs, and salt to the mixture and stir until well combined.
Cover the bowl and let it rise overnight.
Bake
In the morning, preheat the oven to 400°F (200°C).
Pour the batter into pans and bake for 45 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the bulk of the structure that holds the cake together.
- Yeast
- Produces gas during the overnight rise, leavening the dough so it becomes light.
- Eggs
- Add structure and richness, helping the cake set as it bakes.
- Milk
- Provides moisture and hydrates the flour so gluten can develop.
- Butter
- Adds fat for tenderness and richness in the crumb.
The step that matters
Overnight rise. The yeast needs time and warmth to produce enough gas to leaven the dough. A rise that is too short leaves the cake dense, and the dough should be fully covered so its surface does not dry out and form a crust.
