Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. 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
Melt the butter and combine it with the yeast and sugar.
Add 3 cups of flour and mix until light.
Incorporate the beaten egg or yolks and enough flour to knead the dough.
Let the dough rise until it doubles in size.
Shape and bake
Shape the dough into rolls and let them rise again before baking.
Preheat the oven to 400°F (200°C) and bake for 20 minutes.

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
- Yeast
- Ferments the dough, producing gas that makes it rise and become light.
- Butter
- Adds fat for a tender crumb and richer flavor.
- Egg
- Adds structure and richness, helping bind the dough.
- Flour
- Forms the gluten network that gives the rolls their structure.
- Sugar
- Feeds the yeast and adds sweetness and browning.
The step that matters
Letting the dough rise until it doubles. The yeast needs enough time to produce gas and develop the dough's structure. Rising too short leaves rolls dense, while over-proofing can cause them to collapse or lose their structure in the oven.
