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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Rub the butter into the flour.
Add the beaten egg whites, yeast, salt, and enough milk to form a stiff dough.
Cover and set in a warm place until light, about 1 hour or more.
Shape and bake
Shape the dough into round balls.
Dip the edges into melted butter to prevent sticking.
Bake in a moderate oven at 350°F (175°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 structure of the dough and sets the crumb once baked.
- Butter
- Adds fat that tenderizes the rolls and helps browning.
- Egg whites
- Add protein that strengthens the dough and helps it hold its shape.
- Yeast
- Produces gas that makes the dough rise and become light.
- Milk
- Hydrates the flour so the dough can form and develop gluten.
The step that matters
Letting the dough rise until light. Yeast needs time and warmth to produce gas. Underproofed dough stays dense, while a warm, sufficiently long rise lets the gas build an airy crumb.
“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.
