Why it works: Butter and milk 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
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter.
Add the egg yolks and mix well.
Stir in the milk and baking powder.
Fold in the beaten egg whites gently.
Pour the batter into a greased cake pan and bake for 25-30 minutes.
Make the filling
For the filling, boil the milk, sugar, chocolate, and cornstarch for 5 minutes.
Remove from heat and stir in the butter and egg yolks.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites are beaten and folded in to lighten the batter; yolks add richness and help set the filling.
- Butter
- Creamed with sugar to trap air and add tenderness and fat to the cake.
- Sugar
- Sweetens the cake and, creamed with butter, helps create a light texture.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Cornstarch
- Thickens the filling as it boils, giving it a smooth, set texture.
- Chocolate
- Gives the filling its chocolate flavor.
The step that matters
Folding in the egg whites. Beaten egg whites hold air that makes the cake light. Stirring them vigorously deflates that foam, so fold gently and keep the batter airy.
