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.
Prepare the batters
Preheat the oven to 350°F (175°C).
Cream together 1 cup butter and 2 cups white sugar until light and fluffy.
Add ⅓ cup sweet milk and 2 ⅓ cups all‑purpose flour, mixing well. Flavor with lemon.
In another bowl, cream together ⅓ cup butter and ⅓ cup molasses.
Mix in 2 cups all‑purpose flour, spices, 1 heaping teaspoon baking powder, 4 egg whites, 2 small cups brown sugar, 1 cup sour milk, and ¼ teaspoon baking soda. Add 1 whole egg and mix until combined.
Marble and bake
Butter a cake pan well.
Alternate spoonfuls of the dark and white batter until all is used.
Bake in the preheated oven until a toothpick inserted 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
- Butter
- Creams with the sugar to trap air and give the cake a tender, rich crumb.
- Eggs
- Add structure and help bind the batter as they set in the oven.
- All-purpose flour
- Provides the structure that holds the cake together as it bakes.
- Sour milk
- Reacts with the baking soda to lift the batter and adds slight tang and tenderness.
- Molasses
- Gives the dark batter its color, moisture, and a deep, sweet flavor.
- Baking powder
- Releases gas in the batter to make the cake rise and become light.
The step that matters
Alternating the dark and white batter. Spooning the batters in loose alternating layers, rather than stirring them together, keeps the two colors distinct so the marbled pattern forms during baking.
