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 the batters
Preheat the oven to 350°F (175°C).
In a bowl, cream together ½ cup butter and 1½ cups sugar until light and fluffy.
Add 2 cups flour, ½ cup milk, the whites of 4 eggs, ½ teaspoon cream of tartar, and ¼ teaspoon baking soda. Mix well and flavor with lemon.
In another bowl, cream together ½ cup butter and 1 cup sugar.
Stir in ½ cup treacle, 2½ cups flour, ½ cup milk, the yolks of 4 eggs and 1 white, ½ teaspoon baking soda, ½ teaspoon cream of tartar, and spices.
Bake
Drop spoonfuls of the white and dark batter alternately into a greased loaf pan.
Bake for 2 hours in a moderate oven.

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 trap air and add richness and tenderness to the crumb.
- Sugar
- Sweetens the cake and helps the creamed butter hold air for a light texture.
- Flour
- Provides the structure that sets the crumb as the batter bakes.
- Eggs
- Add structure and richness; whites lighten the pale batter and yolks enrich the dark one.
- Treacle
- Gives the dark batter its colour, moisture and molasses flavour.
- Baking soda
- Reacts with the acidic cream of tartar to release gas that makes the cake rise.
The step that matters
Alternating the white and dark batter. Dropping the batters in spoonfuls rather than pouring them keeps two distinct colours for the marble effect. Stirring them together would blend them into one even tan crumb.

Fit is the average pairing score against butter, sugar, flour, milk, egg, cream, molasses. Candidates are from the same food group and used in at least 100 recipes.
