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 ↓
Fruit and Feather Cake
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 the batter
Preheat the oven to 350°F (175°C).
In a large bowl, beat the eggs and sugar until light and fluffy.
Add the softened butter and mix well.
In a separate bowl, combine 1 cup of flour with cream of tartar and baking soda.
Gradually add the flour mixture to the egg mixture, mixing until smooth.
Take out a little less than half of the batter and set aside.
Make the fruit cake and plain cake
To the reserved batter, stir in the remaining flour, raisins, currants, citron, candied peel, nutmeg, cinnamon, brandy, and molasses.
Pour the plain batter into jelly pans and bake until golden.
Assemble and finish
Once baked, layer the plain cake with the fruit cake, covering each layer with jelly.
Ice the top of the stacked cakes.

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
- Beaten with sugar to trap air, giving the cake lift and a light, fluffy structure.
- Butter
- Adds richness and a tender crumb to the batter.
- Flour
- Provides the main structure that sets as the cake bakes.
- Cream of tartar
- Acidifies the batter so baking soda reacts, producing gas that helps the cake rise.
- Baking soda
- Reacts with the acid in the batter to release carbon dioxide for rising.
- Molasses
- Adds moisture, dark colour, and a deep sweetness to the fruit batter.
The step that matters
Folding the remaining flour into the reserved batter. Overmixing develops gluten and makes the fruit cake dense and tough, while the leavening gas already formed can escape if the batter is left standing too long.
Swap the currant
How well each one fits the dish's main ingredients (egg, sugar, butter, flour, cream, raisin, lemon):
- Vanillafits better
- Figfits better
- Blackberryfits better
- Currantthe original
Fit is the average pairing score against egg, sugar, butter, flour, cream, raisin, lemon. Candidates are from the same food group and used in at least 100 recipes.
