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 ↓

Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Rub the butter into the flour until well combined.
Mix all the dry ingredients together.
Mix and bake
Add the buttermilk gradually until the mixture reaches a nice consistency.
Pour the batter into a greased baking pan.
Bake for 2 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the structure that holds the cake together as it bakes.
- Butter
- Rubbed into the flour, it adds richness and tenderness to the crumb.
- Buttermilk
- Its acidity reacts with the baking soda to help the cake rise and keeps it moist.
- Baking soda
- Reacts with the acidic buttermilk to release gas, helping the cake rise.
- Brown sugar
- Adds sweetness and moisture, and contributes to a softer crumb and browning.
The step that matters
Add the buttermilk gradually. Adding liquid in portions lets you judge the batter's consistency and avoid overmixing, which can develop gluten and make the cake dense. Stop once the mixture is just combined and workable.
Swap the nutmeg
How well each one fits the dish's main ingredients (flour, raisin, butter, sugar, buttermilk):
- Cinnamonfits better
- Nutmegthe original
- Jalapenofits about as well
- Capersfits less well
Fit is the average pairing score against flour, raisin, butter, sugar, buttermilk. Candidates are from the same food group and used in at least 100 recipes.
