Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. 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.
Prepare
Preheat the oven to 350°F (175°C).
Beat the whites of 4 eggs until stiff.
Make the light batter
Cream together ½ cup butter and 1 cup white sugar.
Add ½ cup sweet milk to the butter mixture.
Add 2 teaspoons baking powder and 1 teaspoon vanilla or lemon extract to the butter mixture.
Gradually mix in 2½ cups sifted flour.
Make the dark batter
Combine the yolks of 4 eggs in a separate bowl.
Add 1 cup brown sugar, ½ cup cooking molasses and ½ cup sour milk to the yolks.
Add 1 teaspoon ground mace, 1 teaspoon ground cloves and 1 teaspoon ground cinnamon to the yolks mixture.
Dissolve 1 teaspoon baking soda in a little milk, then add it to the yolks mixture.
Mix in 1½ cups sifted flour to the yolks mixture.
Bake
In a well-buttered cake dish, drop spoonfuls of the light batter and dark batter alternately to create a marbled effect.
Bake until a toothpick inserted comes out clean.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Flour
- Forms the cake's structure once its starches set in the oven.
- Eggs
- Yolks add richness and help bind the batter; whites are beaten to add lift.
- Butter
- Adds fat that makes the crumb tender and rich.
- Baking powder
- Releases gas in the batter, helping the light batter rise.
- Baking soda
- Reacts with the acid in sour milk to release gas, helping the dark batter rise.
- Molasses
- Adds moisture, dark color and a deep sweetness to the dark batter.
The step that matters
Dropping the light and dark batters. Spoon the two batters in alternating dollops rather than stirring them together, so they form distinct swirls. Batters of similar thickness hold their pattern better during baking.
Swap the mace
How well each one fits the dish's main ingredients (egg, sugar, butter, milk, vanilla, flour, molasses):
- Cinnamonfits better
- Nutmegfits better
- Clovefits better
- Macethe original
Fit is the average pairing score against egg, sugar, butter, milk, vanilla, flour, molasses. Candidates are from the same food group and used in at least 100 recipes.
