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 ↓
Washington Cake
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).
Make the batter
In a large bowl, mix the eggs, sugar, and butter until well combined.
Add the sour cream and mix thoroughly.
Stir in the mixed fruit and citron.
Gradually add the flour, sherry, brandy, cloves, cinnamon, and nutmeg, mixing until smooth.
Bake
Pour the batter into a well-greased Turk's head mold.
Bake for about 2 hours or until a toothpick inserted comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure as the cake bakes.
- Butter
- Adds richness and tenderness to the crumb.
- Sugar
- Adds sweetness and helps keep the cake moist.
- Flour
- Provides the main structure of the cake.
- Sour cream
- Adds moisture and tang to the batter.
- Mixed fruit
- Adds sweetness, chew, and moisture throughout the cake.
The step that matters
Bake for about 2 hours until a toothpick comes out clean. A dense, fruit-filled batter bakes slowly at a low temperature. Pulling it too early leaves a gummy center, while overbaking dries the crumb, so test the center rather than relying on time alone.
Swap the currant
How well each one fits the dish's main ingredients (egg, sugar, butter, cream, raisin, flour, sherry):
- Vanillafits better
- Figfits better
- Strawberryfits better
- Currantthe original
Fit is the average pairing score against egg, sugar, butter, cream, raisin, flour, sherry. Candidates are from the same food group and used in at least 100 recipes.
