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.
Prepare the batter
Dissolve the chocolate in boiling water.
Cream the butter and gradually add the sugar.
Beat in the egg yolks thoroughly.
Add the dissolved chocolate, cream or milk, flour, baking powder, and vanilla.
Beat the egg whites to a stiff froth and gently fold them into the mixture.
Bake and frost
Pour the batter into a loaf pan or three layer cake pans.
Bake at 350°F (175°C) until a toothpick comes out clean.
Frost with boiled icing flavored with chocolate.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, giving the cake a tender crumb.
- Egg yolks
- Add richness and emulsify the batter, helping it bind smoothly.
- Egg whites
- Whipped to a stiff froth, they add air that helps the cake rise and stay light.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking, causing the cake to rise.
- Sugar
- Sweetens the cake and helps it brown and keep moisture.
The step that matters
Folding in the egg whites. Whites whipped to a stiff froth trap air that gives lift. Stirring them in vigorously knocks that air out, leaving a denser cake, so fold gently with a spatula.
