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 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 batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and butter.
Add the egg and mix well.
Stir in the milk.
Gradually add the flour and baking powder, mixing until smooth.
Pour the batter into greased jelly cake tins.
Bake and make the filling
Bake until a toothpick inserted comes out clean.
For the filling, boil the milk and grated chocolate together.
Remove from heat and stir in the egg yolk, corn starch, and vanilla.
Allow the filling to cool before using.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to add fat and tenderness to the crumb.
- Egg
- Binds the batter and adds structure and richness as it sets.
- Flour
- Provides the main structure that sets as the cake bakes.
- Baking powder
- Releases gas during baking so the cake rises and stays light.
- Grated chocolate
- Gives the filling its chocolate flavour and body when melted into the hot milk.
- Corn starch
- Thickens the filling as it cooks so it sets smooth and spreadable.
The step that matters
Remove from heat and stir in the egg yolk. Adding the yolk to very hot milk can scramble it. Removing the pan from heat first and stirring steadily lets the yolk and corn starch thicken the filling smoothly.
