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 ↓
Duchess 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
Preheat your oven to 350°F (175°C).
Make the batter
In a large bowl, cream together the sugar and butter until light and fluffy.
Add the milk and mix well.
Gradually stir in the flour, followed by the chopped raisins, currants, and citron.
In a separate bowl, combine the cream of tartar, baking soda, cinnamon, cloves, and nutmeg.
Add the dry ingredients to the wet mixture and mix until just combined.
Bake
Pour the batter into a greased cake pan and bake for 30-40 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar, it traps air and adds richness and tender texture.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking soda
- Reacts with the acidic cream of tartar and molasses to help the cake rise.
- Cream of tartar
- Acts as an acid that works with baking soda to produce lift and a lighter crumb.
- Molasses
- Adds moisture, deep flavor, and color, and contributes to browning.
- Raisins
- Add moisture and chewy sweetness scattered through the crumb.
The step that matters
Mixing the dry ingredients into the wet mixture. Mixing only until just combined keeps gluten development limited, so the cake stays tender rather than tough and dense.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, milk, flour, raisin, cream, molasses):

Fit is the average pairing score against sugar, butter, milk, flour, raisin, cream, molasses. 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.
