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.
Make the batter
Cream the butter and sugar together.
Dissolve the chocolate in a little milk.
Add the egg yolks and the rest of the ingredients to the mixture.
Whip the egg whites to a stiff froth and gently fold them in.
Bake and finish
Bake immediately in a moderate oven at 350°F (175°C).
Once cooled, cut the cake in half and add a layer of whipped cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites trap air for lift, while the yolks add richness and help bind the batter.
- Butter
- Adds fat that makes the crumb tender and carries flavor.
- Sugar
- Sweetens the cake and helps keep the crumb soft and moist.
- Flour
- Provides structure that holds the cake together as it bakes.
- Baking powder
- Releases gas when heated, helping the cake rise.
- Grated chocolate
- Gives the cake its main flavor and adds richness.
The step that matters
Folding in the whipped egg whites. Whites must be whipped to a stiff froth and folded gently so their trapped air is kept. Overmixing deflates the batter and makes the cake dense. Baking immediately matters because the baking powder starts releasing gas as soon as it is wet and heated, so a delay loses lift.
