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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the batter
Preheat the oven to 350°F (175°C).
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the flour, raisins, currants, citron, brandy, wine, nutmeg, cinnamon, mace, and cloves until well combined.
In a separate small bowl, mix the vinegar and baking soda.
Stir the mixture into the batter just before pouring it into the baking pan.
Bake
Pour the batter into a greased cake pan.
Bake for about 1.5 to 2 hours, or until a toothpick inserted in the center comes out clean.

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
- Butter
- Creams with the sugar to trap air, giving the cake a light, tender texture and rich flavor.
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Flour
- Provides the main structure that holds the fruit and batter together as the cake bakes.
- Raisins
- Add moisture, sweetness and chewy texture throughout the cake.
- Vinegar
- Reacts with the baking soda to produce gas that helps the cake rise.
- Baking soda
- Reacts with the acidic vinegar to release gas, lifting the batter as it bakes.
The step that matters
Adding the vinegar and baking soda. The vinegar and baking soda release gas as soon as they meet, so the mixture should be stirred in just before the batter goes into the pan. Waiting lets the gas escape, leaving a denser cake.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, butter, egg, raisin, brandy, wine):
- Vanillafits better
- Figfits better
- Applefits about as well
- Currantthe original
Fit is the average pairing score against flour, sugar, butter, egg, raisin, brandy, wine. Candidates are from the same food group and used in at least 100 recipes.
