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 batter
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter until smooth.
Add the egg whites (or whole eggs) and mix well.
In a separate bowl, combine cream of tartar, flour, baking soda, and sweet milk.
Gradually add the dry ingredients to the butter mixture, mixing until just combined.
Divide the batter into three layers and bake until golden.
Make the filling and assemble
For the filling, boil sugar and a little water until it reaches a brittle stage in cold water.
Remove from heat and quickly stir into the beaten egg whites.
Fold in the chopped raisins or hickory nuts.
Spread the filling between the layers and on top of the cake.

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
- Egg whites
- Whipped into the filling, giving it a light, airy, marshmallow-like structure.
- Butter
- Creamed with sugar to add tenderness and richness to the crumb.
- All-purpose flour
- Provides the main structure that holds the layers together.
- Cream of tartar
- Acidifies the batter and stabilizes the beaten egg whites.
- Baking soda
- Reacts with the acidic cream of tartar to lift the layers as they bake.
- Raisins
- Add chewy texture and sweetness to the filling.
The step that matters
Stir the hot sugar syrup into the egg whites. The syrup must be hot and added quickly in a steady stream, as it cooks and sets the whites into a stable, glossy filling. Pouring it in slowly or letting it cool can leave the filling runny or grainy.
Swap the raisin
How well each one fits the dish's main ingredients (sugar, butter, egg, cream, flour, milk):
- Vanillafits better
- Raisinthe original
- Coconutfits less well
- Figfits less well
Fit is the average pairing score against sugar, butter, egg, cream, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
“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.
