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 ↓
Wedding Fruit Cake
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
Preheat the oven to 350°F (175°C).
Mix currants, raisins, and citron with sifted flour.
Cream the butter and sugar together.
Beat the eggs until very light.
Make the batter
Alternately stir the eggs and flour into the butter and sugar mixture, stirring vigorously.
Gradually add the spices and brandy.
Fold in the raisins and fruit mixture.
Stir hard for 10 minutes.
Bake and finish
Bake for 4 to 5 hours.
Ice the cake the next day.

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.

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 and give the cake a tender, rich crumb.
- Sugar
- Sweetens the cake and helps cream with butter to hold air for lightness.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Eggs
- Add structure and richness, and lighten the batter when beaten until very light.
- Raisins
- Add moisture, sweetness and chewy texture throughout the cake.
- Molasses
- Adds moisture, deep sweetness and a dark color to the cake.
The step that matters
Stir hard for 10 minutes. Vigorous mixing develops gluten in the flour, which gives the cake its structure. Too little mixing leaves the batter weak, while the fruit must be folded in evenly so it does not sink.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, flour, molasses, egg, brandy, raisin):
- Vanillafits better
- Figfits better
- Currantthe original
- Applefits about as well
Fit is the average pairing score against butter, sugar, flour, molasses, egg, brandy, raisin. Candidates are from the same food group and used in at least 100 recipes.
