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 the batter
Preheat the oven to 350°F (175°C).
In a large bowl, cream together the sugar and butter.
Add the sweet milk, cream of tartar, baking soda, flour, and eggs; mix well.
Reserve one-third of the batter.
Bake the loaves
Pour the remaining batter into two greased loaf pans and bake until golden.
To the reserved batter, add the raisins, citron, currants, molasses, and mixed spices; mix well.
Pour the fruit batter into a greased loaf pan of the same size and bake until golden.
Assemble and frost
Once cooled, stack the three loaves with icing or currant jelly between them, placing the fruit loaf in the middle.
Frost the top and sides of the cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure that holds the cake's crumb together as it bakes.
- Eggs
- Add structure and richness, helping the batter set and bind during baking.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Sugar
- Sweetens the cake and helps the crust turn golden through browning.
- Baking soda
- Reacts with the acidic cream of tartar and milk to release gas that lifts the batter.
- Molasses
- Adds moisture, dark color, and a deep flavor to the fruit loaf.
The step that matters
Cool the loaves fully before stacking. Warm loaves are soft and crumbly, so stacking them too early can squash or break the layers. Cooling lets the crumb firm up so the icing or jelly holds the layers together cleanly.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, milk, cream, flour, egg, raisin):
- Vanillafits better
- Figfits better
- Coconutfits better
- Currantthe original
Fit is the average pairing score against sugar, butter, milk, cream, flour, egg, raisin. Candidates are from the same food group and used in at least 100 recipes.
