Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Golden Spice-cake
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).
Beat the egg yolks, whole egg, brown sugar, and butter until light and fluffy.
Add the molasses, sour milk, and baking soda. Mix well.
Gradually add the flour, spices, and cayenne pepper. Beat until smooth.
If using raisins, flour them well. Fold the raisins into the batter last.
Bake
Pour the batter into a greased baking pan.
Bake for about 30-40 minutes or until a toothpick comes out clean.

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 for a tender structure.
- Butter
- Adds fat for tenderness and a rich flavor, and helps trap air when creamed.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Molasses
- Adds moisture, dark color, and a deep, slightly bitter sweetness.
- Baking soda
- Reacts with the sour milk to produce gas that lifts the batter.
- Brown sugar
- Sweetens the cake and adds moisture and caramel-like flavor.
The step that matters
Folding in the raisins. Flouring the raisins keeps them suspended in the batter instead of sinking to the bottom during baking. Adding them last, after the batter is smooth, limits overmixing, which would toughen the crumb.
Swap the clove
How well each one fits the dish's main ingredients (egg, sugar, molasses, butter, coffee, milk, flour):
- Cinnamonfits better
- Nutmegfits better
- Gingerfits about as well
- Clovethe original
Fit is the average pairing score against egg, sugar, molasses, butter, coffee, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
