Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and 81,283 recipes mention both. 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
In the evening, mix the flour, sugar, and butter in a bowl.
Stir in the yeast and warm milk until combined.
Cover and let the mixture rise overnight.
In the morning, add enough flour to make a kneadable dough.
Return the dough to the bowl and let it rise again until light.
Shape and rise
Shape the dough into rolls and place them in a baking tin.
Let the rolls rise in a warm place until tea time.
If they need more rising, place them near the stove for a few minutes.
Bake
Bake in a preheated oven at 400°F (200°C) until golden.

Flour and butter share little aroma chemistry, yet 124,287 recipes mention both: they likely 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
- Forms the gluten network that gives the dough its structure and chew.
- Yeast
- Produces gas as it ferments, which makes the dough rise and turn light.
- Butter
- Adds fat that tenderizes the crumb and softens the texture of the rolls.
- Milk
- Adds moisture and some milk sugars that help the crust brown and the crumb stay soft.
- Sugar
- Feeds the yeast during rising and adds sweetness and browning to the crust.
The step that matters
Let the rolls rise in a warm place until tea time.. The rolls need a full proof so the yeast gas fills the dough. Underproofed rolls bake up dense, while overproofed ones can collapse or taste sour.
“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.
