Why it works: Raisin and cinnamon are a kitchen classic. They rank in the top 1% of all ingredient pairs, and cooks put them together in 5,390 recipes. Both carry 1-octen-3-ol, which smells mushroom, earthy. The science ↓
Fruit Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Make the batter
Add the molasses and sour milk, mixing well.
Beat the eggs in a separate bowl, then add them to the mixture.
Incorporate the baking soda, cinnamon, cloves, allspice, nutmeg, and flour, mixing until combined.
Fold in the raisins and currants.
Bake and assemble
Pour the batter into prepared cake pans and bake until a toothpick comes out clean.
Once cooled, layer the cakes and fill with chocolate filling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Add structure and binding, helping the batter hold its shape as it bakes.
- Baking soda
- Reacts with the acid in sour milk and molasses to release gas that lifts the cake.
- Flour
- Provides the structure that holds the cake together as the starches set.
- Butter
- Adds richness and a tender crumb, with creaming trapping air in the batter.
- Molasses
- Adds moisture, sweetness and dark color, and its acidity helps the baking soda work.
- Sour milk
- Adds acidity that activates the baking soda and keeps the crumb tender.
The step that matters
Incorporate the baking soda and flour. Baking soda reacts with the acidic sour milk and molasses to release carbon dioxide. Mixing it in evenly and baking promptly keeps the gas bubbles that give the cake its lift.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, molasses, milk, raisin, egg, cinnamon):
