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
Butter and line your pan with white paper.
Make the batter
Beat butter and sugar until very light.
Stir in one-fourth of the flour.
Whisk eggs until thick, then add gradually.
Add the remainder of the flour, half at a time, beating well.
Mix in the wine, brandy, and spices.
Combine all the fruit and add one-third at a time, beating well.
Bake
Pour in the mixture, smooth it with a knife, and bake at 350°F (175°C) for about four hours.

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
- Butter
- Creams with sugar to trap air, giving the cake a light, tender crumb.
- Eggs
- Add structure and richness, binding the heavy fruit into the batter.
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Raisins
- Add moisture, chewiness and sweetness throughout the cake.
- Currants
- Add moisture, tartness and chewy texture throughout the cake.
- Brandy
- Adds aroma and flavor and helps keep the cake moist.
The step that matters
Adding the fruit and flour in portions. Adding flour and fruit gradually while beating keeps the batter emulsified and evenly mixed, so the heavy fruit does not sink and the cake bakes uniformly.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, flour, egg, raisin, madeira wine, brandy):
- Vanillafits better
- Figfits about as well
- Currantthe original
- Applefits about as well
Fit is the average pairing score against butter, sugar, flour, egg, raisin, madeira wine, brandy. Candidates are from the same food group and used in at least 100 recipes.
