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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the white batter
Preheat the oven to 400°F (200°C).
In a bowl, cream together the white sugar and ½ cup of butter until light and fluffy.
Add the egg whites and mix well.
In another bowl, combine the baking soda with the sour milk and add to the mixture.
Sift together the cream of tartar and flour, then gradually add to the mixture.
Make the brown batter
In a separate bowl, mix the brown sugar, egg yolks, molasses, and ½ cup of butter until smooth.
Dissolve the baking soda in the sour milk and add to the brown mixture.
Stir in the allspice, cloves, and nutmeg.
Marble and bake
Layer the white and brown mixtures in a greased cake pan, swirling them together to create a marble effect.
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
- Adds richness and tenderness to both the white and brown batters.
- Egg whites
- Whipped structure and lift that helps the cake set light and airy.
- Egg yolks
- Add fat and richness to the brown batter, tenderizing the crumb.
- All-purpose flour
- Provides the main structure that sets as the cake bakes.
- Molasses
- Gives the brown batter its dark color, moisture, and deep sweetness.
- Baking soda
- Reacts with the sour milk to produce gas that helps the cake rise.
The step that matters
Marble and bake. Swirling the batters only lightly keeps two distinct patterns; overmixing blends them into an even brown color. Baking until a toothpick comes out clean ensures the centre has set without drying the crumb.
Swap the allspice
How well each one fits the dish's main ingredients (sugar, egg, butter, milk, cream, flour, molasses):
- Cinnamonfits better
- Nutmegfits better
- Gingerfits about as well
- Allspicethe original
Fit is the average pairing score against sugar, egg, butter, milk, cream, flour, molasses. Candidates are from the same food group and used in at least 100 recipes.
