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, flour, baking powder, and eggs; mix well.
Reserve one-third of the batter.
Bake the layers
Pour the remaining batter into two greased cake pans of the same size.
To the reserved batter, add the raisins, citron, currants, molasses, and mixed spices; mix well.
Pour this mixture into a third greased cake pan of the same size.
Bake all three cakes until a toothpick inserted comes out clean.
Assemble and frost
Once cooled, layer the cakes with icing or currant jelly, placing the fruit cake in the middle.
Frost the top and sides of the cake.

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
- Bind the batter and add structure as the cakes set in the oven.
- Butter
- Creams with the sugar to add tenderness and richness to the crumb.
- Flour
- Forms the main structure of the cake crumb as it bakes.
- Baking powder
- Releases gas in the batter so the cakes rise and stay light.
- Raisins
- Add chewy texture and concentrated sweetness to the fruit layer.
- Molasses
- Adds deep sweetness, moisture and a darker color to the fruit batter.
The step that matters
Dividing the batter evenly. The reserved third is split into the fruit layer and the plain layers should match in size so the cakes bake at the same rate and stack level. Baking to a clean toothpick test prevents the fruit layer from staying wet in the centre, since dense batters with fruit need the full bake to set.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, milk, flour, egg, raisin, molasses):
- Vanillafits better
- Figfits better
- Datesfits about as well
- Currantthe original
Fit is the average pairing score against sugar, butter, milk, flour, egg, raisin, molasses. Candidates are from the same food group and used in at least 100 recipes.
