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 dough
Scald the milk and mix it with the butter, sugar, and salt.
Let the mixture cool, then add the yeast.
Pour the mixture into the flour without stirring.
If making in the morning, let it rise until noon.
Mix everything together with a knife and let it stand for 2 hours before tea-time.
Shape and rise
Roll the dough thin, cut into rounds, butter half, and fold them together.
If making at night for breakfast, keep in a cool place to prevent over-rising.
Allow at least 2 hours for the second rise.
Bake
Bake in a 400°F (200°C) oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the gluten network that gives the rolls their structure.
- Yeast
- Produces carbon dioxide gas that makes the dough rise and become light.
- Butter
- Adds richness and tenderness and helps the folded layers separate.
- Milk
- Adds moisture and softness, and its milk sugars help the crust brown.
- Sugar
- Feeds the yeast and adds mild sweetness and browning.
The step that matters
Let the scalded milk cool before adding the yeast. Yeast is a living organism that is killed by very hot liquid. Cooling the scalded milk to lukewarm keeps the yeast alive so the dough can rise properly.
“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.
