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 moderate 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.
Heat the soaked apples through, then remove and chop them finely.
In a pot, combine the chopped apples with molasses and stew until almost soft.
Make the batter
Add sugar, raisins, sour milk, and dissolved baking soda to the pot.
Mix in flour, butter, eggs, cloves, cinnamon, and ginger until well combined.
Bake
Pour the mixture into a baking pan.
Bake in a moderate 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 moisture, giving the cake its soft, chewy fruit texture.
- Molasses
- Adds sweetness, deep color, and moisture, and softens the apples as they stew.
- Baking soda
- Reacts with the acid in the sour milk and molasses to release gas that lifts the cake.
- All-purpose flour
- Forms the main structure that holds the cake together as it bakes.
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Butter
- Adds fat that tenderizes the crumb and gives a rich flavor.
The step that matters
Adding the dissolved baking soda. Baking soda reacts with the acid in the sour milk and molasses and starts releasing gas right away. Mix it in just before baking so the bubbles are trapped in the batter and the cake rises rather than going flat.
Swap the apple
How well each one fits the dish's main ingredients (molasses, sugar, raisin, milk, flour, butter, egg):
- Vanillafits better
- Figfits better
- Datesfits about as well
- Applethe original
Fit is the average pairing score against molasses, sugar, raisin, milk, flour, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
