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 ↓
Tar Heel 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 together the butter and pulverized sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Gradually stir in the flour, then fold in the raisins, currants, citron, orange peel, and chopped almonds.
Mix in the brandy and allspice until well combined.
Bake
Pour the batter into a greased cake pan and bake for several hours 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
- Creams with sugar to trap air, giving the cake a light, tender crumb and rich flavor.
- Eggs
- Add structure and richness, binding the batter as the cake bakes and sets.
- Flour
- Provides the structure that holds the dense batter and fruit together as it sets.
- Raisins
- Add moisture and chewy sweetness throughout the cake.
- Currants
- Add moisture and concentrated tart-sweet fruit flavor throughout the cake.
- Brandy
- Adds aroma and flavor, and its alcohol helps keep the cake moist.
The step that matters
Baking until a toothpick comes out clean. A cake this dense with fruit can look set outside while the center is still wet. Testing the center with a toothpick confirms the batter has fully set before cooling.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, egg, flour, raisin, orange, almond):
- Vanillafits better
- Figfits better
- Lemonfits better
- Currantthe original
Fit is the average pairing score against sugar, butter, egg, flour, raisin, orange, almond. Candidates are from the same food group and used in at least 100 recipes.
