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 ↓
Marble 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and butter until light and fluffy.
Add the sour milk and egg whites, mixing well.
In another bowl, combine the cream of tartar, baking soda, and flour; gradually add to the wet mixture.
Make the batters and bake
In a separate bowl, mix the brown sugar, molasses, butter, sour milk, nutmeg, cinnamon, allspice, cloves, pepper, and egg yolks.
Combine the two mixtures by alternating spoonfuls into a greased cake pan.
Swirl the batters together gently with a knife.
Bake for 30-40 minutes or until a toothpick inserted in the center comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air, giving a light, tender crumb and rich flavor.
- Egg whites
- Add moisture and structure, helping the batter hold air and rise.
- Egg yolks
- Add richness and fat to the darker batter, tenderizing its crumb.
- Flour
- Provides the main structure that sets as the cake bakes.
- Baking soda
- Reacts with the acidic sour milk and cream of tartar to produce gas that lifts the cake.
- Molasses
- Adds moisture, dark color, and a deep sweetness to the darker batter.
The step that matters
Swirl the batters gently. Overmixing the swirl blends the two batters into an even brown color, erasing the marbling. A few gentle passes with a knife keep distinct light and dark streaks while the batters stay separate.
Swap the nutmeg
How well each one fits the dish's main ingredients (sugar, butter, milk, egg, cream, flour, molasses):
- Cinnamonfits about as well
- Nutmegthe original
- Gingerfits less well
- Allspicefits less well
Fit is the average pairing score against sugar, butter, milk, egg, cream, flour, molasses. Candidates are from the same food group and used in at least 100 recipes.
