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 ↓
Grand Duke 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 until light and fluffy.
Add the sweet milk and mix well.
In a separate bowl, beat the egg whites until stiff peaks form.
Combine the flour and baking powder, then gradually add to the butter mixture.
Fold in the beaten egg whites and vanilla.
Bake and fill
Divide the batter into three layers and bake until golden.
For the filling, cook 1 cup sugar and ½ cup water until it forms a syrup that strings.
Stir the syrup into the beaten egg white.
Add the chopped almonds, raisins, and figs to the mixture.
Spread the filling between the layers and ice the top with white icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air, giving the cake a light, tender crumb.
- Egg whites
- Beaten to stiff peaks and folded in, adding lift and an airy structure to the batter.
- Flour
- Provides the main structure that holds the cake's layers together as they set.
- Baking powder
- Releases gas during baking, helping the layers rise.
- Sugar
- Sweetens the cake and, creamed with butter, helps create a light texture.
The step that matters
Cooking the filling syrup to the stringing stage. Sugar syrup that is cooked too little stays runny and soaks the layers, while overcooking makes it hard and brittle. Stopping at the stringing stage gives a filling that holds its shape when spread.
Swap the raisin
How well each one fits the dish's main ingredients (sugar, butter, milk, egg, flour, vanilla, almond):

Fit is the average pairing score against sugar, butter, milk, egg, flour, vanilla, almond. Candidates are from the same food group and used in at least 100 recipes.
