Why it works: Flour and cinnamon are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 17,341 recipes. Both carry isobutyraldehyde, which smells malty, green. 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 dough
Make a sponge as for buns; when light, add the egg and enough flour to make a stiff dough.
Knead the dough and let it rise until it doubles in bulk.
Fill and shape
Roll the dough to 4 inches thick.
Spread the dough with softened butter, then sprinkle with currants, cinnamon, and brown sugar.
Roll the dough and cut it into slices 1 inch thick.
Place the slices in well-greased biscuit or muffin pans, with cut surfaces up and down.
Bake
Let the buns rise until very light, then bake in a moderate oven at 350°F (175°C) for 30 to 40 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the stiff dough structure that holds the buns together and sets in the oven.
- Egg
- Enriches the dough, adding richness and helping it bake to a tender crumb.
- Softened butter
- Adds fat that enriches the dough and helps the spiced filling spread evenly.
- Brown sugar
- Sweetens the filling and caramelizes in the oven for a darker, sticky finish.
- Currants
- Add concentrated sweetness and chewy bursts of fruit throughout the spiral.
- Cinnamon
- Contributes warm, aromatic spice that flavors the filling.
The step that matters
Let the buns rise until very light. Yeast dough needs a full second rise before baking; underproofed buns stay dense and tight, while properly risen dough bakes up light and open.
Swap the currant

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