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 let it cool.
Dissolve the yeast cake in tepid water.
Beat the eggs before adding them to the milk.
Combine all ingredients in the order listed.
Let the mixture rise until doubled in bulk.
Shape and fill
Roll out the dough to ½ inch thick.
Spread melted butter over the dough.
Dredge with sugar, sprinkle with cinnamon, and add currants.
Roll up the dough like a jelly roll and cut into ¾ inch thick slices.
Bake
Place the slices in a baking pan, round side down.
Let them rise again and bake in a 400°F (200°C) oven.

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 buns their structure.
- Yeast
- Produces gas as it ferments, making the dough rise and become light.
- Eggs
- Add richness and help bind the dough, adding tenderness and structure.
- Butter
- Adds fat that tenderizes the dough and carries flavor through the filling.
- Sugar
- Feeds the yeast and adds sweetness, helping the buns brown in the oven.
- Milk
- Adds moisture and richness, softening the crumb of the dough.
The step that matters
Let the mixture rise until doubled in bulk. Yeast needs time to ferment and build gas bubbles; under-proofed dough stays dense, while over-proofed dough can collapse and lose structure.

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