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.
Make the batter
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter until light and fluffy.
Add the milk and eggs, then mix well.
Gradually add the flour and baking powder, and mix until smooth.
Reserve one-third of the batter.
Bake the layers
Pour the remaining batter into two greased cake pans and bake until golden.
Stir the raisins, citron, currants, molasses, and mixed spices into the reserved batter.
Bake the reserved batter in a separate pan until done.
Assemble and frost
Layer the three cakes with icing or jelly.
Place the fruit layer 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
- Butter
- Creams with the sugar to trap air, giving the cake a light, tender crumb and rich flavour.
- Eggs
- Bind the batter and add structure and richness as the cake sets.
- Flour
- Forms the main structure of the cake as the batter sets in the oven.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Raisins
- Add moisture, chewiness and sweetness to the fruit layer.
- Molasses
- Adds dark colour, moisture and a deep, slightly bitter sweetness.
The step that matters
Stir the fruit into the reserved batter. Fruit is heavy and can sink or make the batter wet if overmixed or added unevenly. Stir gently so the fruit is evenly distributed and the layer bakes through without sinking.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, milk, egg, flour, raisin, molasses):
- Vanillafits better
- Figfits better
- Datesfits about as well
- Currantthe original
Fit is the average pairing score against sugar, butter, milk, egg, flour, raisin, molasses. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
