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 ↓
Minnehaha 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 cake
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
In a separate bowl, combine the flour and baking powder, then add to the butter mixture alternately with the milk.
Divide the batter into layers and bake until golden.
Make the filling and icing
For the filling, chop the raisins, figs, dates, and walnuts finely.
Prepare a boiled icing by heating 2 cups of sugar with water until it reaches the soft ball stage, then beat in the egg whites.
Assemble and decorate
Spread the fruit and nut mixture between the layers of cake.
Cover the entire cake with another layer of icing.
Decorate the top and sides with walnut halves while the icing is still soft.

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 trap air, giving the cake a tender, fine crumb.
- Eggs
- Add structure and richness, helping the layers set as they bake.
- Flour
- Forms the cake's structure once its proteins set in the oven.
- Baking powder
- Releases gas during baking so the layers rise and become light.
- Walnuts
- Add texture and fat to the chopped fruit and nut filling.
- Sugar
- Sweetens the cake and, in the icing, cooks to a soft ball stage for a set, glossy coating.
The step that matters
Boiling the icing to the soft ball stage. Sugar syrup must reach the right temperature to set properly. Too little cooking leaves the icing runny, while overcooking makes it hard and grainy. Beating in the egg whites while the syrup is hot creates a stable, fluffy icing.
Swap the dates
How well each one fits the dish's main ingredients (butter, sugar, flour, milk, egg, raisin, fig):
- Vanillafits better

- Datesthe original
Fit is the average pairing score against butter, sugar, flour, milk, egg, raisin, fig. Candidates are from the same food group and used in at least 100 recipes.
