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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Scald the milk and combine it with sugar, butter or lard, and salt.
Let the mixture cool, then add flour and yeast without stirring.
If preparing in the morning, let it rise until noon.
Mix all ingredients together with a knife.
Let the dough stand for 2 hours before tea time.
Shape
Roll the dough thin.
Cut the rolled dough into rounds.
Butter the rounds.
Fold the buttered rounds together.
Bake
Bake in a hot oven at 400°F (200°C).

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 dough its structure and chew.
- Yeast
- Produces gas as it ferments, making the dough rise and become light.
- Milk
- Adds moisture and richness, and helps the dough feel soft and tender.
- Sugar
- Feeds the yeast, adds sweetness, and helps the crust brown.
- Butter or lard
- Adds fat that tenderizes the crumb and layers the folded rounds.
The step that matters
Let the mixture cool before adding the yeast. Yeast is killed by very hot liquid. Scalded milk must cool to a warm, not hot, temperature before the yeast goes in, or the dough will fail to rise.
