Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the batter
Preheat the oven to 350°F (175°C).
In a bowl, beat the egg yolks, brown sugar, and butter until light and fluffy.
Add the molasses, sour cream, and baking soda, mixing well.
Gradually add the flour, ground cloves, cinnamon, ginger, grated nutmeg, and cayenne pepper, and mix until smooth.
If using raisins, flour them well and fold them into the batter last.
Bake
Pour the batter into a greased baking pan and bake for about 30-40 minutes or until a toothpick comes out clean.

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
- Egg yolks
- Add richness and help bind the batter into a tender crumb.
- Butter
- Adds fat for a tender texture and rich flavor.
- Brown sugar
- Adds sweetness, moisture, and a deep caramel-like flavor.
- Molasses
- Adds moisture, dark color, and a robust sweet flavor.
- Baking soda
- Reacts with the acidic sour cream and molasses to help the cake rise.
- Flour
- Provides the structure that holds the cake together as it bakes.
The step that matters
Folding in the raisins. Raisins are heavy and can sink to the bottom of the batter. Flouring them lightly and folding them in last helps distribute them evenly and keeps the batter from being overmixed, which would toughen the cake.
Swap the clove
How well each one fits the dish's main ingredients (egg, sugar, molasses, butter, coffee, cream, flour):
- Cinnamonfits better
- Nutmegfits better
- Gingerfits about as well
- Clovethe original
Fit is the average pairing score against egg, sugar, molasses, butter, coffee, cream, flour. Candidates are from the same food group and used in at least 100 recipes.
