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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batters
Preheat the oven to 350°F (175°C).
Beat the egg whites until frothy.
Cream together the sugar and ½ cup of butter.
Mix the sweet milk with baking soda and add to the butter mixture.
In a separate bowl, combine cream of tartar and flour, then add to the wet ingredients.
Flavor the mixture with lemon.
In another bowl, mix the egg yolks, whole egg, ½ cup of butter, sugar, and molasses.
Add baking soda and flour to the yolk mixture, then stir in spices and fruit.
Bake
Layer the light and dark mixtures in a greased cake pan.
Bake for 30-40 minutes or until a toothpick 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
- Eggs
- Whites are beaten for lightness; yolks and the whole egg add richness and structure.
- Butter
- Creamed with sugar to add fat, tenderness and a rich crumb.
- All-purpose flour
- Provides the structure that holds the cake together as it bakes.
- Cream of tartar
- Acidifies the batter and helps stabilise the whipped egg whites.
- Baking soda
- Reacts with acidic ingredients to produce gas that helps the cake rise.
- Molasses
- Adds sweetness, moisture and the dark colour of the darker batter.
The step that matters
Layering the light and dark mixtures. Pour the batters in loose alternating spoonfuls rather than mixing them, so the light and dark portions stay distinct and the marbled pattern forms during baking.
Swap the lemon

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