Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Marble or Spiced Cake
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°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
Preheat your oven to 400°F (200°C).
Make the batters
In a bowl, cream together the white sugar and butter until light and fluffy.
Add the sour cream or buttermilk and mix well.
Gradually add the flour and baking soda, mixing until combined.
In a separate bowl, cream together the brown sugar and butter.
Add the molasses and sour cream, and mix well.
Incorporate the yolks of 8 eggs and 1 whole egg into the brown mixture.
Combine the mixed spices into the dark batter.
Bake
In a greased pan, layer the light and dark batter alternately.
Bake for about 30-40 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 main structure of the cake as its proteins set during baking.
- Butter
- Adds fat for a tender crumb and a rich flavor.
- Eggs
- Add structure, richness, and help bind the batter.
- Molasses
- Adds moisture, dark color, and a deep, sweet flavor.
- Baking soda
- Reacts with the acidic sour cream to release gas that lifts the batter.
- Sour cream
- Adds moisture and tenderness, and its acidity activates the baking soda.
The step that matters
Gradually add the flour and baking soda, mixing until combined.. Once flour meets liquid, gluten begins to form. Overmixing builds too much gluten, which makes the cake tough and dense, so mix only until the flour is just combined.
