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 overnight in enough cold water to cover them.
Chop the soaked apples in the morning and place them in a pot with the molasses.
Stew the apples and molasses until the apples are almost soft.
Add the raisins and stew for a few more moments.
Make the batter
Let the mixture cool, then add the flour, butter, eggs, and baking soda.
Mix well and pour into baking pans.
Bake
Bake in a steady oven at 350°F (175°C) until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried apples
- Provide moisture and soft, chewy pieces that soften further during stewing and baking.
- Molasses
- Adds sweetness, moisture, and a deep brown color and robust flavor to the cake.
- All-purpose flour
- Forms the gluten network that gives the cake its structure.
- Butter
- Adds fat that tenderizes the crumb and carries flavor.
- Eggs
- Bind the batter and help set the structure as the cake bakes.
- Baking soda
- Reacts with the acidic molasses to produce gas that lifts the batter and deepens browning.
The step that matters
Let the mixture cool before adding the eggs and baking soda. Adding eggs to a very hot mixture can scramble them and melt the butter unevenly. Baking soda reacts with the acidic molasses right away, so the batter should be mixed well and baked promptly to keep its lift.
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.
