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 chocolate custard
Melt the Baker's chocolate.
Mix melted chocolate with ½ cup milk, egg yolk, 2 tablespoons sugar, and 1 teaspoon vanilla.
Cook this mixture like boiled custard.
Make the batter
In a separate bowl, cream together 1 cup sugar and ½ cup butter.
Add ½ cup milk, 2 cups flour, and 1½ teaspoons baking powder to the creamed mixture.
Stir the custard mixture into the cake batter.
Combine all ingredients and mix well.
Bake
Pour the batter into a greased cake pan.
Bake at 350°F (175°C) until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Baker's chocolate
- Provides the chocolate flavour and deep colour of the cake.
- Egg yolk
- Adds richness and helps bind the custard and batter together.
- Flour
- Forms the structure that holds the cake's crumb together as it bakes.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Butter
- Adds fat for tenderness and a rich flavour when creamed with sugar.
- Sugar
- Sweetens the cake and helps tenderise its texture when creamed with butter.
The step that matters
Cooking the chocolate custard. The egg yolk can scramble if the mixture gets too hot or is cooked too fast. Gentle, steady heat and constant stirring keep it smooth, so it thickens evenly before it goes into the batter.
