Why it works: Butter and milk 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 very quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Sift the flour into a bowl.
Rub the butter into the flour until well combined.
Mix in the beaten egg whites and yeast.
Add enough milk and a little salt to form a stiff dough.
Cover the dough and let it rise in a warm place for about 1 hour.
Shape and bake
Cut the risen dough into small rolls.
Place the rolls in a buttered tin and let them rise again.
Bake in a very quick oven at 400°F (200°C) for about 10 minutes.

Flour and butter 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
- Forms the structure that holds the dough together and sets as the rolls bake.
- Butter
- Adds richness and a tender crumb by coating the flour and softening the texture.
- Egg whites
- Add structure and lift through the foam they trap, helping the rolls rise and hold shape.
- Yeast
- Produces gas as it ferments, causing the dough to rise and become airy.
The step that matters
Forming the stiff dough with milk. Too much milk makes the dough slack and it will not hold its shape, while too little leaves it dry and dense. Enough milk to form a stiff dough gives the rolls structure for rising and baking.
“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.
