Why it works: Flour and raisin match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. 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.
Make the dough
Mix flour, baking powder, and salt in a bowl.
Cut in the butter until crumbly.
Gradually add milk until a soft dough forms.
Fill and bake
Roll out the dough to ¼ inch thickness.
Brush with melted butter, then sprinkle with raisins, citron, sugar, and cinnamon.
Roll up the dough like a jelly roll and cut into ¾ inch pieces.
Bake in a 400°F (200°C) oven for 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the dough that holds the rolls together.
- Baking powder
- Releases gas in the dough so the rolls rise and become light.
- Butter
- Adds fat that makes the dough tender and flaky as it is cut in.
- Milk
- Hydrates the flour so it forms a soft, workable dough.
- Raisins
- Add sweetness and chewy moisture to the filling.
The step that matters
Gradually add milk until a soft dough forms. Adding milk all at once can make the dough sticky or tough. Adding it slowly lets the flour absorb the liquid evenly, giving a soft, tender dough that rolls out cleanly.
Swap the raisin
How well each one fits the dish's main ingredients (flour, butter, milk, sugar, cinnamon):
- Vanillafits about as well
- Raisinthe original
- Figfits less well
- Blueberryfits less well
Fit is the average pairing score against flour, butter, milk, sugar, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
