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 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.
Make the batter
Cream the butter and brown sugar together.
Add the molasses, eggs, and brandy. Mix well.
Add the flour and fruit
Sift in the flour and mace.
Fold in the raisins, currants, and citron.
Rub ½ pound of flour with the fruit before adding.
Steam and bake
Steam the mixture in a dish for 2 hours.
After steaming, bake in a moderate oven at 350°F (175°C) for 1 hour.

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
- Creamed with sugar to trap air and give the cake a tender, rich crumb.
- Brown sugar
- Creamed with butter for sweetness and moisture, and it helps the crumb brown.
- Eggs
- Bind the batter and add structure as they set during cooking.
- Flour
- Forms the structure of the cake as its proteins set during cooking.
- Molasses
- Adds moisture, dark color, and a deep, slightly bitter sweetness.
- Brandy
- Adds aroma and flavor to the batter.
The step that matters
Steam before baking. Steaming cooks the dense batter gently with moist heat so it sets through without drying out. Only then should dry oven heat be used to brown the surface; skipping or rushing the steam leaves the centre underdone.
Swap the mace
How well each one fits the dish's main ingredients (butter, sugar, molasses, egg, brandy, flour, raisin):
- Cinnamonfits better
- Nutmegfits better
- Clovefits better
- Macethe original
Fit is the average pairing score against butter, sugar, molasses, egg, brandy, flour, raisin. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
