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.
Make the dark layers
Preheat the oven to 350°F (175°C).
In a bowl, cream together ¾ cup butter and 1½ cups brown sugar until light and fluffy.
Add ¾ cup milk, 3 cups flour, 1½ cups chopped raisins, 3 tablespoons molasses, 5 egg yolks, 1½ teaspoons cinnamon, ¾ teaspoon cloves, and 2 teaspoons baking powder. Mix well.
Pour the dark batter into prepared cake pans and bake until a toothpick comes out clean.
Make the white layers
For the white part, cream together ¾ cup butter and 1½ cups powdered sugar.
Add ¾ cup milk, 3 cups flour, 5 egg whites, and 2 teaspoons baking powder. Mix until smooth.
Pour the white batter into prepared cake pans and bake until a toothpick comes out clean.
Assemble
Once cooled, layer the cakes alternately with boiled icing, placing a white layer on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, giving the cake a tender crumb.
- Eggs
- Egg yolks and whites add structure and richness to the batter as it bakes.
- Flour
- Forms the main structure of the cake as its proteins set in the oven.
- Raisins
- Add chewy texture and sweetness throughout the dark layers.
- Molasses
- Adds moisture, deep flavor, and color to the dark batter.
- Baking powder
- Releases gas in the batter so the cakes rise and turn light.
The step that matters
Creaming the butter and sugar. Beating butter with sugar traps air in the fat, which helps the cake rise and become light. If the butter is too cold or the mixing is too brief, the batter stays dense.
