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 Buns
Ingredients
Directions
The book gives no oven temperature. The 350°F in the steps was added when the recipe was transcribed, as a starting point.
Make the dough
Make a cavity in the center of the flour and stir in the yeast and lukewarm milk until it reaches the thickness of cream.
Cover and let it sit for 2 hours.
Melt the butter until it's oily but not hot, then stir it into the mixture with enough warm milk to form a soft paste.
Sprinkle a little flour over the dough and let it rest for 1 hour.
Shape and bake
Prepare a baking platter by rubbing it with butter.
Mold the dough into buns the size of a large egg and place them 3 inches apart on the platter.
Set the buns in a warm place for 30 minutes or until they double in size.
Bake in a moderate oven (350°F / 175°C) until golden brown.
Brush the buns with milk when removing them from the oven.

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 and lets the buns rise and set.
- Yeast
- Produces gas as it ferments, making the dough rise and become light.
- Butter
- Adds fat that tenderizes the crumb and richness to the buns.
- Sugar
- Provides sweetness and feeds the yeast, and helps the crust brown.
- Milk
- Hydrates the flour and yeast to form the dough and adds softness.
The step that matters
Melting the butter. If the butter is too hot, it can cook the yeast and weaken rising. Melting it only until oily keeps the yeast alive so the dough can rise properly.
