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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Separate the yolks and whites of the eggs.
Prepare three equal-sized buttered shallow cake pans.
Make the batter
Cream the butter and sugar together.
Add the beaten yolks and mix well.
Stir in the milk and then the flour mixed with baking powder.
Fold in the beaten egg whites.
Divide the batter into three parts.
For the third part, mix in the raisins, currants, citron, molasses, brandy, mace, and cinnamon.
Bake and assemble
Bake two pans plain.
Bake the third layer in the third pan.
Once baked, layer the cakes with the fruit layer in the middle, spreading jelly between them.
Press each layer lightly to ensure they stick together.
Trim the edges and frost with plain or boiled frosting.

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
- Yolks enrich and bind the batter, while beaten whites add lift and a light, open crumb.
- Butter
- Fat creamed with sugar traps air and gives the cake a tender, rich texture.
- Sugar
- Creamed with butter, it helps aerate the batter and adds sweetness and tenderness.
- Pastry flour
- Flour provides the structure that holds the layers together after baking.
- Baking powder
- Releases gas in the batter, helping the layers rise and turn light.
- Milk
- Adds moisture that hydrates the flour and keeps the crumb soft.
The step that matters
Folding in the beaten egg whites. Egg whites hold air that gives the layers their lift. Stirring or mixing too hard deflates the foam, so the cakes bake up dense and flat. Fold gently, just until no white streaks remain.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, milk, egg, flour, raisin, molasses):
- Vanillafits better
- Figfits better
- Datesfits about as well
- Currantthe original
Fit is the average pairing score against butter, sugar, milk, egg, flour, raisin, molasses. Candidates are from the same food group and used in at least 100 recipes.
