Why it works: Butter and milk 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 hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Heat the flour.
Cream the yeast and sugar together.
Melt the butter and pour the milk over it.
Mix all ingredients to form a light dough.
Knead well and let rise until doubled in size.
Shape and bake
Re-knead and roll into a square.
Sprinkle with currants and sugar.
Roll up and cut into 1-inch thick pieces.
Let prove for 10 minutes.
Brush with egg and bake at 400°F (200°C) for 15 minutes.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Flour
- Forms the gluten structure that traps gas and gives the bun its body.
- Yeast
- Produces carbon dioxide gas, which makes the dough rise.
- Butter
- Adds fat that tenderises the crumb and carries richness.
- Milk
- Hydrates the flour and adds softness and browning from its milk sugars.
- Sugar
- Feeds the yeast and adds sweetness and browning to the bun.
- Currants
- Add sweet, chewy fruit pieces distributed through the rolled dough.
The step that matters
Knead well and let rise until doubled in size. Kneading develops gluten so the dough can hold gas. Letting it fully double lets yeast build enough gas for a light, airy bun; under-proofed dough bakes dense.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, butter, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Currantthe original
Fit is the average pairing score against flour, sugar, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
