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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Brown the flour in the oven.
Mix the ginger into the molasses.
Steep the mixed spices in the cider overnight.
Prepare a baking pan by greasing it and dusting with flour.
Make the batter
In a large bowl, combine the eggs, butter, brown sugar, browned flour, raisins, currants, citron, and molasses.
Add the steeped cider and spices to the mixture.
Pour the batter into the prepared pan.
Bake
Bake for 3 hours or until a toothpick inserted in the center comes out clean.

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.

Shared aroma: isobutyraldehyde (malty, green).
Butter and flour 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
- Eggs
- Bind the batter and add structure as they set during baking.
- Butter
- Adds richness and tenderness through fat in the crumb.
- Flour
- Provides the structure that sets the cake as it bakes.
- Brown sugar
- Adds sweetness and moisture, and contributes to browning.
- Raisins
- Add chewy texture and concentrated sweetness throughout the cake.
- Molasses
- Adds moisture, deep sweetness, and a darker color to the cake.
The step that matters
Bake until a toothpick comes out clean. A long bake lets the center set fully; pulling the cake early leaves wet batter in the middle, while overbaking dries the fruit-heavy crumb.
Swap the currant
How well each one fits the dish's main ingredients (egg, butter, flour, sugar, raisin, molasses, ginger):
- Vanillafits better
- Figfits better
- Lemonfits better
- Currantthe original
Fit is the average pairing score against egg, butter, flour, sugar, raisin, molasses, ginger. Candidates are from the same food group and used in at least 100 recipes.
