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 ↓
Ribbon Cake
Ingredients
Directions
Make the batter
Beat the egg whites and yolks separately.
Cream the butter and sugar together until light.
Dissolve the baking soda in the milk and add it to the mixture along with the cream of tartar and flour. Beat well and divide the batter into three equal portions.
To one portion, add the egg whites; to another, add the egg yolks; to the third, add the raisins, currants, citron, and spices.
Bake and assemble
Bake each portion separately.
Once baked, layer the cakes with jelly or egg and sugar in between.
Frost the cake and cut it into slices, ensuring the fruit layer is in the center.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites and yolks are added separately to lighten and enrich the layers' structure and colour.
- Butter
- Creamed with sugar to trap air, giving the cake a tender, fine crumb.
- Sugar
- Sweetens the batter and, creamed with butter, helps hold air for a light texture.
- Milk
- Adds moisture and helps the flour form a smooth, even batter.
- All-purpose flour
- Provides the structure that holds the cake layers together.
- Baking soda
- Reacts with the cream of tartar to produce gas that makes the layers rise.
The step that matters
Bake each portion separately. Each batter has different added ingredients and needs its own pan so the layers bake evenly and keep their distinct colours and textures; the leavening reacts quickly, so batter should be baked promptly after mixing.

Fit is the average pairing score against egg, butter, sugar, milk, cream, flour, raisin. Candidates are from the same food group and used in at least 100 recipes.
