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
Prepare the apples
Soak the dried apples overnight.
In the morning, drain and chop the apples finely.
Simmer the chopped apples in molasses for two hours.
When cool, add brown sugar and mixed spices.
Mix and bake
Stir in melted butter, beaten eggs, sour milk, and flour.
Add the dissolved baking soda and lastly the raisins, dredging lightly with flour.
Stir well and bake immediately in papered tins.

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
- Eggs
- Bind the batter and add structure as they set in the oven.
- Baking soda
- Reacts with the sour milk and molasses to produce gas, helping the cake rise.
- Sour milk
- Adds moisture and acidity that activates the baking soda.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Molasses
- Adds moisture, dark color and a deep sweetness to the cake.
- Melted butter
- Adds fat for tenderness and richness in the crumb.
The step that matters
Bake immediately after mixing. Once baking soda is dissolved and combined with the acidic sour milk, it starts releasing gas. Waiting before baking lets much of that lift escape, so the cake may come out flat and dense.
Swap the apple
How well each one fits the dish's main ingredients (raisin, molasses, milk, sugar, egg, butter, flour):
- Vanillafits better
- Figfits better
- Datesfits about as well
- Applethe original
Fit is the average pairing score against raisin, molasses, milk, sugar, egg, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
