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 ↓
Dried Apple 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 in cold water overnight 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 almost soft.
Add the raisins and stew for a few more moments.
Make the batter and bake
When the mixture is cold, stir in the flour, butter, eggs, and baking soda.
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 bulk and fruity flavour, softening into the cake as they stew.
- Molasses
- Adds dark sweetness and moisture, and helps the cake brown.
- All-purpose flour
- Builds the structure that holds the cake together as it bakes.
- Eggs
- Bind the batter and add structure and richness.
- Butter
- Adds fat for tenderness and rich flavour.
- Baking soda
- Reacts with the acidic molasses to lift and lighten the crumb.
The step that matters
Cool the stewed mixture before adding the flour, butter, eggs, and baking soda. Adding eggs and baking soda to a hot mixture can cook the eggs unevenly and cause the baking soda to react too early, so the cake may rise poorly. Letting it cool first keeps the batter smooth and the rise even.
Swap the apple
How well each one fits the dish's main ingredients (molasses, raisin, flour, butter, egg):
- Figfits better
- Vanillafits better
- Datesfits about as well
- Applethe original
Fit is the average pairing score against molasses, raisin, flour, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
