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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
In a large bowl, combine 1 pound of flour, ½ pound of sugar, raisins, currants, mixed peel, almonds, ginger, Jamaica pepper, black pepper, carbonate of soda, cream of tartar, and enough milk to mix thoroughly with your hands.
In another bowl, rub together 1½ cups of flour and ¼ pound of butter or lard until crumbly.
Add ½ teaspoon of baking powder and mix to a fine paste with water.
Assemble and bake
Roll out the paste thinly and line a baking tin, reserving some for the top.
Fill the lined tin with the fruit mixture, flatten the top, and wet the edges.
Cover with the reserved paste and brush with egg white.
Bake at 350°F (175°C) for 2½ hours.

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 and sets around the fruit as it bakes.
- Butter or lard
- Rubbed into the flour to add fat, tenderness and a crumbly texture to the pastry.
- Currants
- Provide the main fruit body, adding moisture and chewy sweetness throughout the bun.
- Large blue raisins
- Add concentrated sweetness and chewy texture to the fruit filling.
- Sugar
- Adds sweetness and helps browning of the crust during baking.
- Baking powder
- Releases gas in the paste to give it lift and a lighter crumb.
The step that matters
Mixing the paste to a fine, even consistency. Rubbing the butter or lard fully into the flour before adding water keeps the fat distributed, which makes the pastry tender rather than tough. Adding water too early or unevenly leaves pockets of gluten-forming dough that toughen the crust.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, raisin, almond, ginger, pepper, cream):

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