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 ↓
Fruit Layer 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 batter
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter.
Add 1½ cups of flour, sherry wine, raisins, and 2 eggs, mixing well.
Stir in 1½ teaspoons of baking powder.
Divide the batter into three layers and bake until golden.
Make the second layer and frosting
For the second layer, mix 1 scant cup of flour, 3 eggs, melted butter, milk, 2 teaspoons of baking powder, and vanilla.
Bake in two layers.
For the frosting, beat the whites of 2 eggs and gradually add powdered sugar until thick.
Prepare boiled icing flavored with vanilla.
Assemble
Layer strawberries, sliced oranges, coconut, bananas, grated chocolate, or walnuts between the cake layers and on top of the icing.

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 sugar to give the batter tenderness and a rich flavor.
- Flour
- Provides the structure that holds the cake layers together.
- Eggs
- Bind the batter and help set the structure as it bakes.
- Baking powder
- Releases gas during baking so the layers rise and stay light.
- Sugar
- Sweetens the batter and helps the layers brown.
- Raisins
- Add chewy moisture and concentrated sweetness to the batter.
The step that matters
Baking the layers until golden. Under-baked layers stay wet and collapse, while over-baking dries the crumb. Baking powder needs prompt, steady heat to lift the batter, so check the layers near the end of the time given and do not open the oven early.
Swap the raisin
How well each one fits the dish's main ingredients (sugar, butter, flour, sherry, wine, egg, milk):
- Vanillafits better
- Figfits about as well
- Raisinthe original
- Applefits about as well
Fit is the average pairing score against sugar, butter, flour, sherry, wine, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
