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 ↓
Plain Rolls
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the sponge
Scald the milk and pour it over the butter, sugar, and salt.
When the mixture is cool, dissolve the yeast cake in the lukewarm water and add it.
Stir in the flour to make the sponge and beat well; let it rise until light.
Knead and shape
Add enough flour to knead the dough; knead thoroughly and set aside to rise.
When the dough is light, punch it down, shape it into rolls, let them rise again, and bake in a hot oven at 400°F (200°C).

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
- Forms the gluten structure that traps gas and gives the rolls their body.
- Yeast
- Produces carbon dioxide as it ferments, making the dough rise and become light.
- Milk
- Adds moisture and richness, producing a softer crumb in the finished rolls.
- Butter
- Adds fat, which tenderizes the crumb and gives a softer bite.
- Sugar
- Feeds the yeast and contributes sweetness and gentle browning in the oven.
The step that matters
Letting the sponge rise until light. The yeast needs time to ferment the flour and sugar and build gas bubbles before the dough is kneaded. Rising too briefly leaves the rolls dense, while the cooled mixture must be warm enough for yeast to stay active but not hot enough to kill it.
