Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Chocolate Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the cake batter
Preheat the oven to 350°F (175°C).
Beat the sugar and butter together until creamy.
Add the egg yolks and mix well.
In a separate bowl, beat the egg whites until stiff peaks form.
Dissolve the cream of tartar and baking soda in the milk, then add to the mixture.
Gradually mix in the flour until combined.
Fold in the beaten egg whites gently.
Make the filling
For the filling, melt the chocolate and mix with powdered sugar, milk, and beaten egg.
Bake and fill
Bake the cake in two tins and spread the filling while hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks add richness and the whipped whites add lift and structure to the cake.
- Butter
- Creamed with sugar, it adds fat that gives the cake a tender crumb.
- Sugar
- Sweetens the cake and helps the butter cream to a light texture.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Cream of tartar and baking soda
- Together they react to produce gas that helps the cake rise.
- Chocolate
- Gives the cake its chocolate flavour and makes the filling rich and set.
The step that matters
Folding in the beaten egg whites gently. The whites trap air that makes the cake rise. Stirring hard or vigorously deflates that foam, leaving a dense, flat cake.
