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 brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the dough
Pour the scalded milk over the salt, sugar, and butter.
When lukewarm, beat in 4 cups of flour.
Mix well and add the dissolved yeast foam.
Cover closely and let rise in a warm place.
When light, add enough more flour (4 cups) to knead.
Cover and let rise until light.
Shape and bake
Roll out to ½ inch thickness.
Shape with a biscuit cutter.
Brush each shape with melted butter.
Crease through the center. Fold over. Press edges together.
Place in a buttered pan 1 inch apart and let rise until very light.
Bake in a brisk oven at 400°F (200°C) for 15 minutes.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Butter and flour 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
- Flour
- Builds the gluten structure that traps gas and gives the rolls their soft, chewy crumb.
- Yeast foam
- Produces carbon dioxide as it ferments sugars, making the dough rise and turn light.
- Milk
- Adds moisture and richness, and its proteins help give a tender, browned crumb.
- Butter
- Adds fat that tenderizes the crumb and gives a rich flavor and golden color.
- Sugar
- Feeds the yeast and adds sweetness and gentle browning to the crust.
The step that matters
Letting the dough rise until light before shaping. Yeast gas must fully expand the gluten network; rising too little leaves dense rolls, while over-proofing weakens the structure so rolls collapse or bake flat.
“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.
