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 ↓
Prince of Wales 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.
Prepare the batters
Preheat the oven to 350°F (175°C).
For the dark part, cream together ½ cup butter and 1 cup brown sugar.
Add 4 egg yolks, ½ cup sour milk, 1 cup chopped raisins, 5 teaspoons baking soda, 1 tablespoon molasses, ½ tablespoon ground cloves, 1 tablespoon ground cinnamon, and ½ nutmeg. Mix well.
For the white part, cream together 1 cup butter and 1 cup white sugar.
Add 4 egg whites, ½ cup sweet milk, 1 cup corn starch, and 1 cup flour. Mix well.
If not using corn starch, add 2 cups flour instead.
Bake and assemble
Bake both mixtures in layers.
Layer the dark and white cakes alternately with icing in between.
Flavor with lemon.

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 sugar to give the cake a tender, rich crumb.
- Flour
- Forms the main structure that holds the cake together as it bakes.
- Brown sugar
- Adds sweetness and moisture, and deepens the color and flavor of the dark layer.
- Egg yolks
- Add richness and help bind the batter into a stable structure.
- Egg whites
- Whipped structure helps the light white layer rise and stay airy.
- Corn starch
- Softens the crumb and makes the white layer lighter and more tender.

How well each one fits the dish's main ingredients (butter, flour, sugar, milk, raisin, egg, molasses):
- Cinnamonfits better
- Nutmegfits better
- Gingerfits about as well
- Clovethe original
Fit is the average pairing score against butter, flour, sugar, milk, raisin, egg, 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.
