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 ↓

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.
Make the sponge
Set a sponge at 9 o'clock at night with warmed milk and yeast; stir in enough flour to mix smoothly.
When the sponge is very light the next morning, cream together the butter and sugar, then add the eggs.
Dissolve the baking soda in a little water and mix it into the sponge along with the egg mixture.
Gradually sift in enough flour to make a stiff batter that can be stirred with a wooden spoon.
Shape and rise
Let the batter rise again until very light, then pinch off pieces slightly larger than an egg and shape them gently.
Place the shaped dough on buttered paper in pans, ensuring they do not touch each other, and let them rise again.
Bake and frost
Bake in a 350°F (175°C) oven until very slightly brown.
Frost with a mixture of egg white and sugar.

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
- Yeast
- Ferments the sponge, producing gas that makes the dough light and airy.
- Eggs
- Add structure and richness, helping the batter set and hold its shape.
- Butter
- Adds fat and tenderness, giving the dough a rich texture.
- Sugar
- Adds sweetness and helps the crumb brown lightly in the oven.
- Baking soda
- Reacts with the batter's acidity to add lift and a tender crumb.
- Flour
- Provides the structure that holds the batter and shaped dough together.
The step that matters
Letting the dough rise fully before shaping and baking. Yeast needs time to build gas and lightness; shaping or baking before the dough is very light leaves rolls dense. Leaving space between pieces lets each one expand without merging.
“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.
