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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Make the batters
For the white part, cream together the butter and egg whites.
Add the sweet milk, sifted flour, and baking powder to the mixture.
For the dark part, cream the butter and brown sugar.
Mix in the sour milk, baking soda, sifted flour, and beaten egg yolks.
Add the ground spices to the dark mixture.
Bake
In a prepared pan, layer the white and dark mixtures alternately.
Bake for 1.5 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Unsalted butter
- Creams with the sugar to trap air and give the cake a tender, rich crumb.
- Egg whites
- Add structure and lift to the white batter as they set in the oven.
- Egg yolks
- Add richness and moisture to the dark batter and help it bind.
- Baking powder
- Releases gas in the white batter so it rises and becomes light.
- Baking soda
- Reacts with the sour milk to lift the dark batter and tenderize it.
- Brown sugar
- Adds sweetness, moisture, and the deep color of the dark batter.
The step that matters
Layering the white and dark mixtures. Alternating the two batters in the pan creates the marbled pattern. Over-stirring them together after layering blends the colors and loses the marble effect, so layer gently.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
