Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. 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 until light and fluffy.
Mix the grated chocolate, flour, and baking soda into the butter and sugar mixture.
Add the egg yolks one at a time, mixing well after each addition.
Fold and bake
Beat the egg whites until stiff peaks form.
Gently fold the beaten whites into the batter.
Pour the mixture into a pan lined with buttered parchment paper.
Bake in a moderate oven at 350°F (175°C) for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg whites trapped by beating add lift, and yolks add richness and structure to the crumb.
- Baking soda
- Reacts with the batter to produce gas, helping the cake rise and turn lighter.
- Flour
- Its proteins set during baking, giving the cake its structure.
- Butter
- Creamed with sugar to trap air, and adds fat for tenderness and flavour.
- Granulated sugar
- Creamed with butter to build a light texture and adds sweetness and browning.
- Grated chocolate
- Provides the chocolate flavour and adds richness to the batter.
The step that matters
Folding in the beaten egg whites. Stirring vigorously deflates the foam trapped in the whites, which is what lifts the cake. Fold gently, so the batter keeps its air and rises evenly in the oven.
