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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the light batter
Preheat oven to 350°F (175°C).
In a bowl, cream together the white sugar and ½ cup butter. Add ⅓ cup sweet milk, 2½ cups flour, 1 teaspoon baking soda, 1 teaspoon cream of tartar, and the whites of 4 eggs. Mix well and flavor with lemon extract or nutmeg.
Make the dark batter
In another bowl, cream together the brown sugar and ½ cup butter. Add ⅓ cup sweet milk, ⅓ cup molasses, the yolks of 4 eggs, 1 teaspoon baking soda, 2 teaspoons cream of tartar, and 2½ cups flour. Season with cinnamon, nutmeg, and cloves.
Bake and serve
Drop the two batters alternately into a baking dish.
Bake 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
- Eggs
- Whites add lift and structure in the light batter, while yolks add richness and tenderness to the dark batter.
- Baking soda
- Reacts with the acidic cream of tartar and molasses to produce gas that makes the cake rise.
- Cream of tartar
- Acid that reacts with the baking soda to help the batters rise and keeps the crumb tender.
- Flour
- Forms the structure of the cake that holds its shape as it bakes.
- Butter
- Adds fat for tenderness and flavor and helps trap air when creamed with sugar.
- Molasses
- Adds moisture, dark color, and a deep sweetness to the dark batter.
The step that matters
Dropping the two batters alternately. Batters that are dropped in unevenly or stirred too much blend into one color and lose the marbled look. Light, spaced spoonfuls keep the two batters distinct, and gentle handling keeps the rise from collapsing.
