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 hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Pour hot milk over butter, salt, and sugar. Let cool.
Dissolve yeast cake in lukewarm water. Add to the cooled milk mixture.
Stir in 3 cups of flour to make a sponge. Beat well and let rise.
Once light and spongy, add more flour to form a stiff dough. Knead until smooth and elastic.
Let the dough rise until doubled in size. Knead again if necessary.
Shape the rolls
Roll the dough to ½ inch thick. Let it rest before cutting.
Cut with a round or oval cutter.
Place a bit of butter near the edge, fold over, and press to seal.
Place rolls on a baking sheet to rise.
Bake and serve
Once light, bake in a hot oven at 400°F (200°C).
For breadsticks, roll a small piece of dough into a stick about 1 foot long and the diameter of a little finger. Bake breadsticks in a moderate oven at 350°F (175°C) until brown.

Butter and flour 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
- All-purpose flour
- Forms the gluten network that gives the dough structure and a soft, chewy crumb.
- Yeast
- Ferments sugars to produce gas that makes the dough rise and become light.
- Butter
- Adds fat that tenderizes the crumb and gives a rich flavor.
- Milk
- Adds moisture and milk sugars that help browning and a tender texture.
- Sugar
- Feeds the yeast and adds sweetness and browning in the crust.
The step that matters
Knead until smooth and elastic. Kneading develops the gluten network that traps the gas from the yeast. Too little kneading leaves a dense, weak dough that rises poorly.
“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.
