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 ↓

Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batters
Preheat the oven to 400°F (200°C).
In a bowl, cream together 1 cup of butter and 3 cups of white sugar.
Add 5 cups of flour, ½ cup of sweet milk, ½ teaspoon of baking soda, and the whites of 8 eggs. Mix well and flavor with lemon extract.
In another bowl, cream together 1 cup of butter, 2 cups of brown sugar, and 1 cup of molasses.
Stir in 1 cup of sour milk, 1 teaspoon of baking soda, 4 cups of flour, the yolks of 8 eggs, and 1 whole egg. Add spices to taste.
Bake
In a prepared baking pan, layer the dark batter, then the white batter, repeating until all batter is used, finishing with a dark layer.
Bake in the preheated oven 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
- Butter
- Creams with sugar to give the batter structure and a tender crumb.
- All-purpose flour
- Provides the main structure that sets as the cake bakes.
- Eggs
- Whites lighten the light batter and yolks enrich the dark batter, adding structure.
- Molasses
- Adds moisture, deep colour and sweetness to the dark batter.
- Baking soda
- Reacts with the acidic sour milk and molasses to make the cake rise.
- Sour milk
- Its acidity activates the baking soda and tenderises the crumb.
The step that matters
Layering the dark and white batters. The two batters are thick and differ in colour and density, so layering them carefully keeps the marbled pattern distinct instead of blending into one shade.
