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 ↓
Federal 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 the batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the brown sugar and butter.
Add the sour milk and eggs, mixing well.
Dissolve the baking soda in the sour milk and add to the mixture.
In another bowl, combine the flour and baking powder.
Gradually add the flour mixture to the wet ingredients.
Fold in the chopped raisins, walnuts, cinnamon, cloves, allspice, and vanilla.
Bake
Pour the batter into a greased cake pan and bake for 30-40 minutes or until a toothpick comes out clean.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to add richness and a tender crumb.
- Eggs
- Bind the batter and add structure as the cake sets.
- Baking soda
- Reacts with the acidic sour milk to produce gas that lifts the batter.
- Baking powder
- Adds additional lift so the cake rises evenly in the oven.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Raisins
- Add chewy pockets of sweetness throughout the crumb.
The step that matters
Dissolving the baking soda in the sour milk. Baking soda needs an acid to activate it. Dissolving it fully in the sour milk before mixing spreads the reaction evenly, so the cake rises without holes or bitter patches.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, butter, milk, egg, flour, raisin, cinnamon):
- Almondfits better
- Chestnutfits better
- Pistachiofits about as well
- Walnutthe original
Fit is the average pairing score against sugar, butter, milk, egg, flour, raisin, cinnamon. 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.
