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
Make the batter
Cream together the butter and sugar until light and fluffy.
Sift the baking powder with the flour and add to the creamed mixture.
Stir in the milk and fold in the beaten egg whites.
Make the middle layer
For the middle layer, take out 4 tablespoons of the batter and mix in the molasses, ⅓ cup flour, raisins, cloves, baking soda, cinnamon, and egg yolks.
Bake and assemble
Bake the three layers separately.
Layer the middle layer between the other two with jelly or soft icing.
Ice the top.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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, giving the cake a light, tender crumb and rich flavor.
- Egg whites
- Beaten and folded in to add lift and structure as the cake bakes.
- Baking powder
- Releases gas in the batter, helping the layers rise.
- Molasses
- Adds moisture, dark color, and a deep, slightly bitter sweetness to the middle layer.
- Raisins
- Add chewy texture and concentrated sweetness to the middle layer.
- Baking soda
- Reacts with the acidic molasses to help the middle layer rise and darken.
The step that matters
Make the middle layer batter. Baking soda needs an acid, such as the molasses, to react and leaven properly. Measure the soda carefully, because too much leaves a soapy, bitter taste and uneven rise.
Swap the clove
How well each one fits the dish's main ingredients (butter, sugar, flour, milk, egg, molasses, raisin):
- Cinnamonfits better
- Nutmegfits better
- Gingerfits about as well
- Clovethe original
Fit is the average pairing score against butter, sugar, flour, milk, egg, molasses, raisin. Candidates are from the same food group and used in at least 100 recipes.
