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 ↓

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 sponge
Dissolve the yeast in a little warm water to prepare a sponge.
Mix the sponge with enough flour to form a batter and let it rise until doubled in size.
Make and rise the dough
On a floured surface, make a well in 1 pound of flour and add the butter, milk, eggs, salt, and the risen sponge.
Work the mixture together, adding flour as needed.
Cover and let it rise in a warm place for 3 hours.
Roll out the dough and fold it three times.
Shape and bake
Remove about a quarter of the dough, shape the remainder into a round, slightly flattened top.
Shape the smaller piece into a ball, flatten it, and place it on top of the larger piece.
Glaze with beaten egg, place on a buttered baking tin, and bake at 400°F (200°C) for 45 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
- Provides the structure that holds the dough together and traps the gas produced by the yeast.
- Fresh butter
- Adds fat that makes the crumb tender and rich.
- Eggs
- Add richness, structure and colour to the dough.
- Milk
- Adds moisture to the dough, softening the crumb.
- German yeast
- Produces gas that makes the dough rise and become light.
The step that matters
Letting the dough rise fully. The rise depends on live yeast activity in a warm place. If the dough is cold or underproofed, it will stay dense, and overproofing can make it collapse and lose structure.
“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.
