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 ↓
Fine Fruit Cake
Ingredients
Directions
The book says “a steady oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the apples
Soak the dried apples overnight in cold water to swell them.
Chop the soaked apples in the morning and place them in a pot with the molasses.
Stew the mixture until the apples are soft but not pulpy.
Make the batter
Let the mixture cool, then mix in the flour, butter, eggs, and baking soda.
Add salt and spices to taste, and raisins if desired.
Bake
Bake in a steady oven at 350°F (175°C) until done.

Flour and butter 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
- Dried apples
- Provide the fruity bulk and moisture, softening into the body of the cake.
- Molasses
- Adds sweetness, moisture and deep brown colour, and softens the crumb.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Butter
- Adds fat for richness and a tender texture.
- Eggs
- Bind the batter and add structure as they set during baking.
- Baking soda
- Reacts with the acidic molasses to produce gas that helps the cake rise and darken.
The step that matters
Stew the apples until soft but not pulpy. Stewing softens the apple's cell walls so it blends into the batter, but overcooking breaks the fruit down into a mush that makes the cake wet and dense, so the apples should stay soft yet hold some shape.
Swap the raisin
The recipe marks raisin as optional. How well each one fits the dish's main ingredients (apple, molasses, flour, butter, egg, allspice):
- Raisinthe original
- Figfits about as well
- Pearfits less well
- Vanillafits less well
Fit is the average pairing score against apple, molasses, flour, butter, egg, allspice. Candidates are from the same food group and used in at least 100 recipes.
