Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Chocolate Cake
Ingredients
Directions
The book says “a quite hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 400°F (200°C).
Cream together the sugar and butter.
Add the well-beaten eggs, then mix in the milk and flour.
Melt the chocolate and add it to the mixture along with the vanilla extract.
Bake and frost
Pour the batter into a greased cake pan and bake for about 30-35 minutes.
For the frosting, mix the confectioner's sugar, milk, and melted butter until smooth.
Spread the frosting over the cooled cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Butter
- Creams with the sugar to trap air and adds richness and tenderness.
- Sugar
- Sweetens the cake and helps it brown while creaming aerates the batter.
- All-purpose flour
- Provides the main structure that sets as the cake bakes.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Chocolate
- Adds chocolate flavour and some richness and moisture to the crumb.
The step that matters
Cream the sugar and butter. Beating sugar and butter together traps air bubbles that expand in the oven and lighten the crumb. Under-creamed butter leaves a dense, heavy cake.
