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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the sponge
Make a sponge with milk, yeast cake, 1 tablespoon sugar, lukewarm water, and salt. Beat thoroughly.
Let rise until light.
Make and shape the dough
Add eggs and enough flour to make a stiff dough. Knead.
Let rise until it doubles in bulk.
Roll the dough to ½ inch thick.
Spread with softened butter, currants, cinnamon, and brown sugar.
Roll the dough like a jelly roll.
Cut into slices 1 inch thick.
Bake
Place in a greased pan with cut surfaces up and down.
Bake in a moderate oven at 350°F (175°C) for 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 stiff dough its structure and chewy crumb.
- Yeast cake
- Ferments the sugars in the sponge, producing gas that makes the dough rise.
- Eggs
- Add richness and structure, helping the enriched dough set into a tender crumb.
- Milk
- Provides moisture and tenderness, and its sugars help the crust brown in the oven.
- Butter
- Adds fat for tenderness and richness, and spreads flavour through the layered filling.
- Brown sugar
- Sweetens the filling and caramelises during baking, adding moisture and colour.
The step that matters
Let the dough double in bulk. Yeast needs time to produce enough gas to expand the gluten network. Under-proofed dough bakes dense, while over-proofed dough can collapse and lose its shape.

Fit is the average pairing score against milk, sugar, flour, egg, butter, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
