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 Fudge 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. 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
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the egg yolks and mix well.
In a separate bowl, beat the egg whites until stiff peaks form.
Make the batter
Combine the flour and baking powder, then add to the butter mixture alternately with the milk.
Fold in the chopped nuts and melted chocolate last.
Pour the batter into two greased cake pans.
Bake and finish
Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.
Cool and frost as desired, or cut into squares like fudge.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and tenderness, and holds air when creamed with sugar.
- Sugar
- Sweetens the cake and helps create a light, aerated creamed base.
- Eggs
- Yolks add richness and emulsify the batter; whites beaten to stiff peaks add lift and structure.
- Flour
- Provides the structure that sets the cake as it bakes.
- Baking powder
- Releases gas in the batter, making the cake rise and become light.
- Chocolate
- Adds deep chocolate flavour and richness to the cake.
The step that matters
Cream the butter and sugar until light and fluffy. Beating butter with sugar traps tiny air pockets in the fat. These pockets expand in the oven and help the cake rise and stay tender, so stopping early leaves a dense crumb.
Swap the nuts
How well each one fits the dish's main ingredients (butter, sugar, egg, flour, milk, chocolate, vanilla):
- Almondfits better
- Hazelnutfits better
- Chestnutfits better
- Nutsthe original
Fit is the average pairing score against butter, sugar, egg, flour, milk, chocolate, vanilla. Candidates are from the same food group and used in at least 100 recipes.
