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 ↓
Raisin Layer 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).
In a bowl, cream together the butter and sugar until light and fluffy.
Add the egg yolks and milk, mixing well.
Gradually add the flour and cream of tartar, stirring until smooth.
In another bowl, beat the egg whites until stiff peaks form.
Fold the beaten egg whites into the batter gently.
Pour the batter into a greased cake pan and bake for 25-30 minutes.
Make the raisin filling
For the filling, combine ⅓ cup sugar and 3 tablespoons water in a saucepan and boil for 5 minutes.
Slowly pour the syrup over the beaten egg whites, then add the chopped raisins.
Beat the mixture until cool and spread it between the layers of the cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich and set the crumb, while beaten whites add lift and an airy structure.
- Butter
- Fat that creams with sugar to trap air and gives the cake a tender texture.
- Sugar
- Sweetens the cake and helps create a light, creamed batter and a syrup for the filling.
- Flour
- Provides the main structure that sets the cake as it bakes.
- Cream of tartar
- Stabilizes the beaten egg whites so they hold their peaks.
- Raisins
- Add sweetness, chewy texture and moisture to the filling.
The step that matters
Fold the beaten egg whites into the batter gently. Folding keeps the air trapped in the whipped whites. Stirring or overmixing deflates the foam, so the cake rises less and bakes up denser.
Swap the raisin
How well each one fits the dish's main ingredients (egg, butter, sugar, milk, flour, cream, syrup):
- Vanillafits better
- Raisinthe original
- Figfits less well
- Strawberryfits less well
Fit is the average pairing score against egg, butter, sugar, milk, flour, cream, syrup. 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.
