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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream the butter in a bowl.
Gradually add the sugar, then the beaten egg yolks, and beat again.
Stir in the boiling water with the melted chocolate.
Add the flour and mix well.
Finish and bake
Beat the egg whites until stiff and gently fold them into the batter.
Add the vanilla and baking powder, then pour the batter into a greased cake pan.
Bake for 45 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich the batter and whites, beaten stiff, give the cake lift and a light crumb.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Butter
- Creamed with sugar to trap air and add richness and tenderness.
- Sugar
- Sweetens the cake and helps create a tender texture when creamed with butter.
- Chocolate
- Gives the cake its chocolate flavour and adds moisture when melted into the batter.
- Baking powder
- Releases gas during baking so the cake rises and becomes lighter.
The step that matters
Folding in the egg whites. Stiffly beaten whites hold air that makes the cake light. Folding gently keeps that air in; vigorous stirring deflates the batter and leaves a dense cake.
