Why it works: Raisin and flour 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 ↓
Excellent 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.
Make the batter
Preheat the oven to 350°F (175°C).
In a large bowl, mix the butter and brown sugar until creamy.
Add the eggs one at a time, mixing well after each addition.
Stir in the lemon juice and baking powder.
Gradually add the flour, mixing until combined.
Fold in the raisins, currants, and citron.
Bake and finish
Pour the batter into a greased loaf pan.
Bake for 2 hours or until a toothpick comes out clean.
While warm, pour ½ pint of wine over the cake.

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
- Bind the batter and add structure as they set during baking.
- Butter
- Creamed with sugar, it traps air and adds richness and tenderness.
- Brown sugar
- Adds sweetness, moisture, and a caramel-like depth of flavor.
- Flour
- Forms the structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas in the batter, helping the cake rise.
- Raisins
- Add chewy texture and concentrated sweetness throughout the cake.
The step that matters
Adding the eggs one at a time. Adding eggs gradually and mixing well lets them emulsify into the creamed butter and sugar. Adding them all at once can cause curdling, which hurts the batter's texture.
Swap the currant
How well each one fits the dish's main ingredients (raisin, butter, sugar, flour, egg, lemon):
- Vanillafits better
- Figfits better
- Orangefits better
- Currantthe original
Fit is the average pairing score against raisin, butter, sugar, flour, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
