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 moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the sponge
Soften the yeast in warm water.
In a bowl, combine the softened yeast, beaten egg white, melted butter, sugar, warm milk or water, and salt.
Add enough flour to make a sponge and let it sit overnight.
Shape and bake
In the morning, knead the dough well and let it rise again until light.
Roll out the dough to about ¾ inch thick and cut out shapes using a large cookie cutter or saucer.
Butter the edges of each piece and roll each side towards the center.
Place the rolls in buttered tins and let them rise until light.
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
- Yeast
- Ferments the dough, producing gas that makes it rise and become light.
- Flour
- Forms the gluten network that gives the dough structure and holds the risen gas.
- Egg white
- Adds protein for structure and helps the rolls set with a fine texture.
- Butter
- Adds fat that softens the crumb and gives a richer flavor and tender texture.
- Sugar
- Feeds the yeast and adds sweetness and some browning in the oven.
- Milk
- Adds moisture and milk solids that soften the crumb and aid browning.
The step that matters
Letting the rolls rise until light. Yeast needs time and warmth to produce enough gas for a light texture. Rolls baked before they have risen fully stay dense and heavy.
“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.
