Why it works: Chocolate and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Chocolate 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
Preheat the oven to 350°F (175°C).
Make the batter
In a large bowl, cream together the brown sugar and butter.
Add the eggs and sour cream, mixing well.
Stir in the dissolved chocolate mixture and vanilla extract.
In a separate bowl, combine the flour and baking soda.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Bake
Pour the batter into a greased cake pan and 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
- Brown sugar
- Adds sweetness and moisture, and helps give the cake a soft, tender crumb.
- Butter
- Adds fat for richness and a tender texture when creamed with the sugar.
- Eggs
- Add structure and help bind the batter as it sets in the oven.
- Sour cream
- Adds moisture and acidity, which keeps the crumb tender.
- Flour
- Provides the structure that sets the cake as it bakes.
- Baking soda
- Reacts with the acidic sour cream to produce gas that helps the cake rise.
The step that matters
Stirring in the dry ingredients. Once flour meets liquid, gluten begins to form. Stirring only until combined keeps the batter tender, while overmixing produces a tough, dense cake.
