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 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a large bowl, mix the flour, sugar, molasses, and butter until well combined.
Add the eggs one at a time, mixing well after each addition.
Stir in the currants, raisins, and citron.
In a separate bowl, combine the baking soda, cloves, cinnamon, and spice.
Add the dry mixture to the wet mixture, alternating with the wine or water.
Bake
Pour the batter into a greased cake pan and bake for about 1 hour.

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 cake together as it bakes.
- Butter
- Adds fat for tenderness and a rich texture.
- Eggs
- Bind the batter and add structure and richness.
- Sugar
- Sweetens the cake and helps it brown during baking.
- Molasses
- Adds sweetness, moisture and deep color to the cake.
- Baking soda
- Reacts with the acidic molasses to help the cake rise.
The step that matters
Adding the dry mixture alternately with the wine or water. Alternating keeps the batter emulsified and evenly moistened, so the flour is not overworked and the texture stays tender rather than tough.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, molasses, egg, butter, raisin, clove):
- Vanillafits better
- Figfits better
- Applefits better
- Currantthe original
Fit is the average pairing score against flour, sugar, molasses, egg, butter, raisin, clove. Candidates are from the same food group and used in at least 100 recipes.
