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 ↓
Chocolate Marble
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.
Make the batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and butter.
Add the sweet milk and eggs, mixing well.
In another bowl, combine the flour, baking soda, and cream of tartar.
Gradually add the dry ingredients to the wet mixture.
Marble and bake
Dissolve the chocolate in a little boiling water and mix with ½ cup sugar and 2 tablespoons of the dough. Flavor the chocolate mixture separately.
Pour the batter into a greased baking pan and swirl in the chocolate mixture.
Bake for 30-35 minutes or until a toothpick comes out clean.

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 main structure once its proteins set with heat.
- Sugar
- Adds sweetness and helps keep the crumb tender and moist.
- Butter
- Adds fat that tenderizes the crumb and carries flavor.
- Eggs
- Bind the batter and add moisture and structure as they set.
- Baking soda
- Reacts with the acid in the batter to release gas that makes the cake rise.
- Chocolate
- Gives the dark swirls and a rich cocoa flavor.
The step that matters
Swirling the chocolate into the batter. Swirl gently with only a few strokes. Overmixing blends the chocolate evenly into the batter, losing the marbled pattern and making the crumb denser.
