Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and 81,283 recipes mention both. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

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 dough
Boil the milk.
Let the milk cool.
Stir in the flour with a spoon until it absorbs the milk.
Add sugar, yeast, and butter.
Set aside to rise.
Shape into a loaf using minimal flour.
Let it rise for about 1 hour.
Shape and bake
Roll out the dough to cookie thickness.
Cut with a cookie cutter.
Place a little butter in the center. Fold.
Place in a tin.
Let rise again.
Bake in a 400°F (200°C) oven for about 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the gluten network that gives the rolls their structure.
- Yeast
- Ferments the dough so it rises and becomes light and airy.
- Milk
- Adds moisture and richness, and its proteins help soften the crumb.
- Butter
- Adds fat that tenderizes the crumb and enriches the flavor.
- Sugar
- Feeds the yeast and adds sweetness and gentle browning.
The step that matters
Let the milk cool before adding the yeast. Boiled milk must cool to a warm, not hot, temperature before it is mixed with yeast, because high heat can kill the yeast and stop the dough from rising.
“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.
