Why it works: Milk and butter 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.
Prepare the dough
Scald the milk and let it cool.
Make a hole in the flour and add the cooled milk, sugar, butter, and yeast.
Let the dough rise
Let the mixture stand overnight.
Mould the dough and let it rise until noon.
Shape and bake
Shape into rolls and let them rise until supper.
Bake in a preheated oven at 400°F (200°C) until golden.

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 rolls their structure.
- Milk
- Adds moisture and richness, and its sugars help the crust brown.
- Sugar
- Adds sweetness, feeds the yeast, and helps the crust brown.
- Butter
- Adds fat that makes the crumb tender and soft.
- Yeast
- Produces gas during the long rise, which leavens the dough.
The step that matters
Letting the dough rise. Yeast needs time and warmth to produce gas that stretches the gluten. Rising too little leaves dense rolls, while rising too long weakens the structure and can make them collapse in the oven.
“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.
