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 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 300°F (150°C).
Make the batter
Cream the butter and sugars together.
Add the cinnamon, cloves, molasses, and sour milk to the mixture.
Incorporate the beaten egg yolks.
Gradually add the sifted flour, alternating with the beaten egg whites.
Dissolve the baking soda in warm water and mix it in.
Toss the raisins, currants, and citron with 2 tablespoons of flour, then fold into the batter.
Bake
Pour the batter into a prepared pan and bake for 2 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich the batter and whites, folded in, add lightness and help structure.
- Butter
- Creamed with the sugar, it traps air and gives the cake a tender, rich crumb.
- Flour
- Forms the structure of the cake as its proteins set during baking.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce gas that helps the cake rise.
- Molasses
- Adds moisture, deep sweetness, and color to the batter.
- Sour milk
- Its acidity activates the baking soda and tenderizes the crumb.
The step that matters
Folding the fruit into the batter. Dusting the raisins, currants, and citron with flour helps them stay suspended instead of sinking to the bottom during baking. Fold gently so the batter keeps the air trapped in it.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, egg, raisin, molasses, milk, cinnamon):
- Vanillafits better
- Figfits better
- Applefits better
- Currantthe original
Fit is the average pairing score against butter, sugar, egg, raisin, molasses, milk, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
