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 ↓
With Twenty-four Eggs. Fruit Cake.
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Beat the egg whites to a stiff froth and thoroughly beat the yolks.
Mix the fruit, spices, and flour together.
Combine all ingredients and mix thoroughly.
Bake and store
Bake in a preheated oven at 300°F (150°C) for 5 to 6 hours for a large loaf.
Store covered in a stone jar for long-lasting freshness.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 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
- Flour
- Provides the structure that holds the dense fruit and batter together as it bakes.
- Eggs
- Whites trap air for lift, while yolks add richness, moisture and binding.
- Butter
- Adds fat that makes the crumb tender and rich in flavor.
- Sugar
- Adds sweetness and helps the crust brown during long baking.
- Raisins
- Add moisture, sweetness and chewy texture throughout the loaf.
- Currants
- Add moisture, tartness and chewy texture throughout the loaf.
The step that matters
Beating the egg whites to a stiff froth. Stiff whites hold air bubbles that give the heavy, fruit-filled batter lift. If they are under-beaten, the loaf will be denser, and deflating them by over-mixing loses that air.
Swap the mace
How well each one fits the dish's main ingredients (flour, raisin, currant, butter, sugar, egg, cinnamon):
- Nutmegfits better
- Allspicefits better
- Clovefits better
- Macethe original
Fit is the average pairing score against flour, raisin, currant, butter, sugar, egg, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
