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 ↓
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 bowl, cream together the butter and brown sugar.
Add the beaten eggs and mix well.
Combine the milk and wine, then add to the mixture.
Dredge the raisins in some of the flour and fold them into the batter.
Gradually add the remaining flour and mix until combined.
Bake
Pour the batter into a greased cake pan and bake for 2 hours.

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
- Creams with the sugar to add richness and a tender crumb.
- Eggs
- Bind the batter and add structure as the cake sets.
- Flour
- Forms the main structure of the cake as it bakes.
- Brown sugar
- Adds sweetness, moisture, and a deeper caramel flavour.
- Raisins
- Add chewy texture and pockets of sweetness throughout the cake.
The step that matters
Dredge the raisins in flour before folding. Coating the raisins in a little flour helps them stay suspended in the batter instead of sinking to the bottom during baking.
Swap the nutmeg
How well each one fits the dish's main ingredients (sugar, butter, flour, egg, milk, wine, raisin):
- Cinnamonfits better
- Nutmegthe original
- Capersfits less well
- Jalapenofits less well
Fit is the average pairing score against sugar, butter, flour, egg, milk, wine, raisin. 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.
