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.
Prepare the cake
Preheat the oven to 350°F (175°C).
Cream together the granulated sugar and butter until smooth.
Add the egg whites (or whole eggs) and mix well.
In a separate bowl, combine cream of tartar, sifted flour, and baking soda.
Gradually add the dry ingredients to the butter mixture, alternating with sweet milk, and mix until smooth.
Divide the batter into three layers.
Bake until golden.
Make the filling and assemble
Boil 1 cup of sugar with a little water until it reaches a brittle stage in cold water.
Remove from heat.
Quickly stir into the beaten egg white.
Fold in the chopped raisins or hickory nuts.
Spread the filling between the layers.
Spread the filling on top of the cake.

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
- Eggs
- Egg whites add structure and lift to the batter as they set during baking.
- Butter
- Creaming with sugar traps air and adds richness and a tender crumb.
- Flour
- Provides the structure that holds the layers together once baked.
- Baking soda
- Reacts with the acid in the cream of tartar to produce gas that helps the cake rise.
- Cream of tartar
- Acidifies the batter so it reacts with baking soda and keeps the egg whites stable.
- Granulated sugar
- Sweetens the cake and helps create a soft, tender texture when creamed with butter.
The step that matters
Boil the sugar to the brittle stage and stir it into the egg white quickly. Sugar cooked to the correct stage sets into a firm, glossy filling when it cools. If it is undercooked the filling stays runny, and if it cools before it is stirred in, it can set lumpy.
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.
