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. 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 the batters
Preheat the oven to 350°F (175°C).
In a bowl, mix 1 cup flour, ½ cup cornstarch, ½ cup sweet milk, ½ cup softened butter, 1 cup sugar, 2 teaspoons baking powder, and the egg whites until smooth.
In another bowl, combine 1 cup dark brown sugar, ½ cup softened butter, ½ cup sour milk, 2 cups flour, chopped raisins, 1 teaspoon baking soda, 1 tablespoon molasses, cinnamon, nutmeg, egg yolks, lemon peel, and cloves.
Layer and bake
Layer the white batter and dark batter in a greased cake pan.
Bake for about 30-40 minutes or until a toothpick inserted in the center comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the main structure that sets the crumb as the cake bakes.
- Butter
- Adds fat for a tender texture and rich flavor in both batters.
- Egg whites
- Add structure and lift to the light batter as they set in the oven.
- Egg yolks
- Add richness and moisture to the dark batter and help it set.
- Baking soda
- Reacts with the sour milk and molasses to lift and darken the dark batter.
- Dark brown sugar
- Adds moisture and molasses-like sweetness that deepens the color of the dark batter.
The step that matters
Layering the two batters. The light and dark batters are thick and similar in weight, so pouring them carelessly can mix them into one color. Spooning them in gently keeps the layers distinct as they bake.
“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.
