Why it works: Flour and butter 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 ↓

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
Combine flour, yeast, salt, and sugar in a bowl.
Add eggs one at a time, mixing until a smooth paste forms.
Add an additional egg or yolk if needed to achieve a workable dough.
Dust a cloth with flour and roll the dough in the floured cloth.
Place the dough in a pan.
Let the dough rise in a cool place in summer or a warm place in winter, preferably overnight.
Knead the dough again in the morning.
Shape and bake
Divide the dough into uniform balls.
Press a thumb into the top of each ball to create a hollow.
Place a smaller ball of dough into each hollow.
Brush each hollow with egg yolk and glaze the tops with egg yolk.
Bake in a preheated oven at 400°F (200°C) for 30 minutes or until golden.

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
- All-purpose flour
- Provides the structure that holds the dough together and lets it rise.
- Yeast
- Produces gas during rising, which leavens the dough and gives it an airy crumb.
- Butter
- Adds fat that tenderizes the crumb and gives brioche its rich texture.
- Eggs
- Add structure, moisture, and richness to the dough, and their yolk glaze promotes browning.
- Sugar
- Feeds the yeast and contributes sweetness and browning to the crust.
The step that matters
Adding eggs and the rising time. Eggs must be mixed in gradually so the dough emulsifies into a smooth, workable paste. Overly soft dough can be hard to shape, so an extra egg is added only if needed. A long, slow rise lets the yeast develop flavor and 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.
