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 quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Mix the butter and sugar together.
Beat the egg yolks well and add them to the mixture.
Stir in the chocolate and a little salt.
Sift the baking powder with the flour, then add the flour and cream alternately.
Fold in the beaten egg whites until stiff.
Bake
Bake in three layers as for jelly cake.

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, lighten it for a tender crumb.
- Butter
- Fat that creams with sugar and adds tenderness and richness to the crumb.
- Baking powder
- Releases gas in the batter so the cake rises and stays light.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Sugar
- Sweetens the cake and helps hold moisture in the crumb.
- Cream
- Adds moisture and richness to the batter.
The step that matters
Fold in the beaten egg whites until stiff. Whites hold air only when beaten stiff and folded gently, so the batter keeps its lift. Overmixing or deflating them makes the cake dense and flat.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
