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
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter and sugar together.
Add the beaten yolks of the eggs. Mix well.
Sift the flour and baking powder together.
Add the sifted flour and baking powder to the mixture along with the milk.
Fold in the beaten egg whites gently.
Divide the batter into three parts.
Bake and assemble
Bake two parts as plain cake in a moderate oven (350°F / 175°C) for about 20 minutes.
Add the raisins, currants, citron, molasses, cinnamon, and mace to the third part. Bake the third part.
Layer the cakes with jelly in between.

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
- Butter
- Creams with sugar to trap air and add richness and tenderness to the crumb.
- Sugar
- Sweetens the cake and helps hold air when creamed with the butter.
- Eggs
- Yolks add richness and structure; beaten whites give lift and a light texture.
- Flour
- Forms the structure of the cake as it sets in the oven.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Raisins
- Add chewy sweetness and fruit flavour to the dark layer.
The step that matters
Folding in the beaten egg whites gently. Stirring hard knocks out the air trapped in the whites, so the batter loses its lift and the cake bakes up dense.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, egg, flour, milk, raisin, molasses):
- Vanillafits better
- Figfits better
- Datesfits about as well
- Currantthe original
Fit is the average pairing score against butter, sugar, egg, flour, milk, raisin, molasses. Candidates are from the same food group and used in at least 100 recipes.
