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 ↓
Marbled Cake
Ingredients
Directions
The book says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the light batter
Preheat the oven to 350°F (175°C).
For the light part, cream together white sugar and butter.
Add sweet milk, baking soda, cream of tartar, and egg whites; mix well.
Gradually add flour until combined.
Make the dark batter
For the dark part, cream together brown sugar and molasses with butter.
Add sour milk, baking soda, cream of tartar, and egg yolks; mix well.
Gradually add flour and spices until combined.
Marble and bake
In a greased pan, alternate spoonfuls of light and dark batter to create a marbled effect.
Bake for 30-40 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that sets the cake crumb as the batter bakes.
- Egg whites
- Add lift and a light, airy texture to the light batter.
- Egg yolks
- Add richness and tenderness to the dark batter.
- Butter
- Adds fat for a tender crumb and rich flavor in both batters.
- Molasses
- Adds moisture, dark color, and a deep sweet flavor to the dark batter.
- Baking soda
- Reacts with the acidic sour milk and molasses to help the cake rise.
The step that matters
Alternating the light and dark batter. Dropping spoonfuls of each batter in turn creates the marbling. Stirring them together would blend the two colors into one uniform batter, so the pattern is lost.
Swap the clove
How well each one fits the dish's main ingredients (sugar, butter, milk, cream, egg, flour, molasses):
- Cinnamonfits better
- Nutmegfits better
- Gingerfits about as well
- Clovethe original
Fit is the average pairing score against sugar, butter, milk, cream, egg, flour, molasses. Candidates are from the same food group and used in at least 100 recipes.
