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
Cream the butter and sugar together.
Add the milk, flour, and baking powder, mixing well.
Beat the egg whites to stiff peaks and fold them into the batter.
Divide the batter into three layers and bake at 350°F (175°C) until golden.
Make the icing and assemble
For the icing, boil 2 cups of sugar with 7 tablespoons of water until it forms a thin string.
Beat 2 egg whites to a froth and gradually stir in the boiling sugar.
Fold in the raisins and walnuts, then spread the icing on the layers.

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 and give the cake a tender, rich crumb.
- Egg whites
- Whipped to stiff peaks to lighten the batter and help it rise in the oven.
- Flour
- Forms the main structure of the cake as it sets during baking.
- Baking powder
- Releases gas in the batter, making the layers rise and turn light.
- Sugar
- Sweetens the cake and, boiled with water, forms the icing's syrup.
The step that matters
Boiling the icing sugar to a thin string. The sugar syrup must reach the right concentration before it is poured into the beaten egg whites. Undercooked syrup leaves the icing runny, while overcooked syrup turns hard and grainy as it cools.
Swap the walnut
How well each one fits the dish's main ingredients (butter, sugar, egg, milk, flour, vanilla, raisin):
- Almondfits better
- Chestnutfits better
- Pistachiofits about as well
- Walnutthe original
Fit is the average pairing score against butter, sugar, egg, milk, flour, vanilla, raisin. Candidates are from the same food group and used in at least 100 recipes.
