Why it works: Raisin and flour 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 ↓
Hickory-nut 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 the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the beaten eggs gradually, mixing well.
Stir in the raisins, currants, hickory nuts, citron, and sweet milk.
In a separate bowl, combine the flour and baking powder, then add to the mixture.
Flavor with lemon and nutmeg to taste.
Bake
Pour the batter into a large cake pan.
Bake for about 2 hours or until a toothpick inserted in the center comes out clean.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Butter
- Creamed with sugar to trap air, giving the cake a light, tender crumb and rich flavor.
- Eggs
- Add structure and richness, and help bind the batter as it sets in the oven.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas in the batter, helping the cake rise and turn light.
- Sugar
- Sweetens the cake and, creamed with butter, helps create a fine, tender texture.
- Raisins
- Add moisture and chewy sweetness throughout the cake.
The step that matters
Adding the beaten eggs gradually. Adding eggs slowly lets the emulsion of butter and sugar stay stable. Adding them all at once can cause curdling, which may leave the cake dense.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, egg, raisin, milk, flour, lemon):
- Vanillafits better
- Figfits better
- Blackberryfits better
- Currantthe original
Fit is the average pairing score against butter, sugar, egg, raisin, milk, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
