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 hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the dough

  1. Preheat the oven to 400°F (200°C).

  2. In a bowl, mix flour, baking powder, salt, sugar, and butter until crumbly.

  3. Stir in milk, raisins, citron, and chopped nuts to form a dough.

  4. Roll out the dough to ½-inch thick.

Fill and bake

  1. Brush with melted butter and sprinkle with additional fruit, sugar, and cinnamon.

  2. Roll up the dough tightly and cut into pieces.

  3. Place on a buttered baking sheet and bake 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 structure that holds the rolled dough together as it bakes.
Baking powder
Releases gas in the oven, lifting the dough so the rolls rise and stay tender.
Butter
Adds richness and tenderness, and browns the outside of the rolls.
Milk
Hydrates the flour so the mixture comes together into a soft dough.
Raisins
Add pockets of sweetness and moisture within the rolled dough.

The step that matters

Roll up the dough tightly and cut into pieces. A loose roll can unravel or leave gaps in the spiral, so the filling spills out and the pieces bake unevenly. Rolling snugly keeps each piece's layers intact.

Swap the nuts

How well each one fits the dish's main ingredients (flour, sugar, butter, milk, raisin):

  1. Almondfits better
  2. Chestnutfits better
  3. Pistachiofits better
  4. Nutsthe original

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