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 ↓
Tutti-frutti 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
Cream together the sugar and butter until smooth.
Add the sweet milk, flour, and baking powder; mix well.
Bake in layers at 350°F (175°C).
Make the filling
For the filling, boil the granulated sugar and boiling water until it stands alone when poured from a spoon.
Slowly pour the syrup over the whipped egg whites, stirring until cool.
Fold in the raisins and chopped walnuts.
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 to form a foam that gives the cooked filling a light, airy texture.
- Butter
- Creams with the sugar to add fat, tenderness and richness to the cake crumb.
- Baking powder
- Releases gas in the batter, helping the layers rise and turn light.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Granulated sugar
- Boiled with water into a syrup that sweetens and sets the filling.
The step that matters
Pouring the boiling syrup over the egg whites. The syrup must be poured slowly while the whites are whipped and stirred, so the hot sugar cooks and stabilises the foam instead of scrambling the egg or deflating it.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, butter, milk, flour, egg, raisin):
- Almondfits better
- Chestnutfits better
- Pistachiofits about as well
- Walnutthe original
Fit is the average pairing score against sugar, butter, milk, flour, egg, raisin. Candidates are from the same food group and used in at least 100 recipes.
