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 starter
Mix warm milk with small beer yeast.
Strain the mixture.
Add fine flour until the mixture is the stiffness of batter.
Cover the mixture.
Let rise in a warm place.
Make the dough
Cream together butter, powdered sugar, and coarse sea salt.
Incorporate the remaining flour into the creamed mixture.
Make a hole in the center of the dough.
Pour the risen batter into the hole.
Sprinkle flour over the dough and cover.
Knead the dough until smooth.
Let rise in a warm place.
Shape and bake
Shape the dough as desired.
Place the dough on tin plates.
Let rise for 20 minutes.
Bake in a 400°F (200°C) oven until golden brown.

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
- Small beer yeast
- Ferments the batter, producing gas that makes the dough rise.
- Fine flour
- Provides the structure that traps gas and sets the crumb as the bread bakes.
- Butter
- Adds fat, which tenderises the crumb and carries flavour.
- Warm milk
- Adds moisture and proteins that help browning and a soft crumb.
- Powdered loaf sugar
- Feeds the yeast and helps the crust brown.
The step that matters
Let the batter rise until bubbly before adding flour. The yeast needs warmth and time to ferment the starter. If it is underproofed, the dough will be dense; the rise develops the gas that lightens the loaf.
“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.
