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 ↓
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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, cream together the butter, brown sugar, and molasses.
Add the sour milk and egg yolks, mixing well.
In a separate bowl, combine the baking soda, cream of tartar, and flour.
Gradually add the dry ingredients to the wet mixture.
Fold in the chopped raisins, currants, cloves, cinnamon, and nutmeg.
Bake
Pour the batter into a greased cake pan and bake for about 45 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat that gives the cake a tender crumb and rich flavor.
- Egg yolks
- Add richness and emulsify the batter, helping it bind and set.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce gas that lifts the cake.
- Molasses
- Adds moisture, dark color, and a deep sweetness with slight acidity.
- Sour milk
- Supplies acidity that activates the baking soda and tenderizes the crumb.
The step that matters
Gradually add the dry ingredients to the wet mixture. Adding flour in portions and mixing gently keeps the batter smooth and limits gluten development, which would otherwise make the cake tough. Overmixing also deflates the gas bubbles that the leavening creates.
Swap the raisin
How well each one fits the dish's main ingredients (butter, sugar, molasses, milk, egg, cream, flour):
- Vanillafits about as well
- Raisinthe original
- Figfits less well
- Strawberryfits less well
Fit is the average pairing score against butter, sugar, molasses, milk, egg, cream, flour. Candidates are from the same food group and used in at least 100 recipes.
