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 ↓
Deied Apple Cake
Ingredients
Directions
Prepare the apples
Soak the dried apples overnight.
In the morning, boil the soaked apples slowly in dark molasses for 2 hours.
Make the batter
Add sugar, butter, sour milk, flour, raisins, walnuts, citron, candied oranges, and lemon peel to the mixture.
Stir in cloves, allspice, cinnamon, nutmeg, baking soda, and baking powder, then mix well and keep as a fruit cake.

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
- All-purpose flour
- Provides the starch and gluten network that gives the cake its structure.
- Butter
- Adds fat that tenderizes the crumb and carries flavor.
- Sour milk
- Adds moisture and acidity that reacts with the baking soda to help the cake rise.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce gas that lifts the batter.
- Dark molasses
- Adds moisture, deep color, and a rich, slightly acidic sweetness.
- Sugar
- Adds sweetness and helps keep the cake moist and tender.
The step that matters
Boiling the apples in molasses. Simmering slowly for the full 2 hours softens the apples and thickens the molasses. Boiling too hard or too high can scorch the thick sugary mixture on the bottom of the pan.
Swap the walnut
How well each one fits the dish's main ingredients (apple, molasses, sugar, butter, milk, flour, raisin):
- Almondfits better
- Chestnutfits better
- Pistachiofits about as well
- Walnutthe original
Fit is the average pairing score against apple, molasses, sugar, butter, milk, flour, raisin. Candidates are from the same food group and used in at least 100 recipes.
