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 the light batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together 1 ½ cups sugar and ½ cup butter until light and fluffy.
Add ½ cup sweet milk, 2 cups flour, 1 teaspoon cream of tartar, and ½ teaspoon baking soda. Mix well.
Fold in the beaten egg whites gently.
Make the dark batter
In another bowl, mix 1 cup brown sugar, ½ cup molasses, ½ cup sour milk, 2 cups flour, and 1 teaspoon cream of tartar.
Add ½ teaspoon baking soda, 4 egg yolks, and spices (cloves, cinnamon, allspice, nutmeg). Mix until smooth.
Bake
In a greased pan, alternate layers of the light and dark batter.
Bake for 30-40 minutes or until a toothpick inserted comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites give lift, and yolks add richness and tenderness to the batter.
- Butter
- Creamed with sugar, it traps air and gives the light batter a tender, fine crumb.
- All-purpose flour
- Its proteins set into the cake's structure as the batter bakes.
- Cream of tartar
- Acidifies the batter and helps stabilise the leavening reaction with baking soda.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce gas that helps the cake rise.
- Molasses
- Adds moisture, dark colour, and a deep sweetness to the dark batter.
The step that matters
Folding in the beaten egg whites. Whipped whites hold air that gives the cake lift; stirring vigorously deflates them and leaves a dense cake, so fold gently until just combined.
Swap the clove
How well each one fits the dish's main ingredients (sugar, butter, milk, flour, cream, egg, molasses):
- Cinnamonfits better
- Nutmegfits better
- Gingerfits about as well
- Clovethe original
Fit is the average pairing score against sugar, butter, milk, flour, cream, egg, molasses. Candidates are from the same food group and used in at least 100 recipes.
