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.
Make the batter
Dissolve the chocolate in boiling water.
Cream the butter and gradually add the sugar.
Mix in the beaten egg yolks, then add the cream or milk and dissolved chocolate.
In a separate bowl, combine the flour and baking powder, then add to the chocolate mixture.
Fold in the vanilla and beaten egg whites.
Bake
Bake in a loaf or layer cake pans at 350°F (175°C) 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
- Butter
- Creamed with sugar to trap air, giving the cake a tender crumb and rich flavor.
- Egg whites
- Whipped to stiff peaks, they add lift and an airy structure to the batter.
- Egg yolks
- Add richness and emulsify the batter, helping it bake moist and tender.
- Flour
- Provides the structure that sets as the cake bakes.
- Baking powder
- Releases gas in the oven, helping the cake rise.
- Chocolate
- Supplies the chocolate flavor and deep color of the cake.
The step that matters
Fold in the beaten egg whites. Folding gently keeps the air whipped into the egg whites. Stirring vigorously deflates the batter, leading to a denser, flatter cake.
