Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Apple Fruit-cake
Ingredients
Directions
Prepare the apples
Chop the soaked apples finely.
Boil the apples in molasses for 2 hours or more.
Make the batter
In a bowl, cream together the butter and sugar.
Add the milk, eggs, and baking soda to the mixture.
Stir in spices and enough flour to make a stiff batter, similar to pound cake.
Fold in the boiled apples and optional citron.

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
- Dried apples
- Provide the fruit bulk and tender texture once softened and boiled in molasses.
- Molasses
- Adds deep sweetness, dark colour and a rich, slightly sharp flavour.
- Butter
- Adds fat for richness and a tender crumb when creamed with sugar.
- Sugar
- Sweetens the batter and helps create a light structure when creamed with butter.
- Eggs
- Add structure and binding so the batter holds together as it bakes.
- Baking soda
- Reacts with the molasses acidity to help the cake rise and darken.
The step that matters
Boiling the apples in molasses. The apples must cook long enough to soften fully, since they will not get tender once baked into a stiff batter. Keep the heat gentle so the molasses does not scorch on the bottom of the pan.
Swap the apple

Fit is the average pairing score against molasses, butter, sugar, milk, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
