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 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 the batter
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter.
Add the sour milk, eggs, and flour, mixing well.
Make the chocolate filling
In a separate bowl, mix the grated chocolate with sweet milk and the yolk of one egg.
Sweeten the chocolate mixture to taste and add vanilla.
Cook the chocolate mixture until it thickens, then cool.
Combine the cooled chocolate mixture with the cake batter.
Bake and frost
Pour the batter into a greased cake pan and bake for 30-35 minutes.
Once baked, frost with confectioner's sugar.

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.
- Eggs
- Add structure and richness to the batter and bind it together.
- Flour
- Provides the main structure of the cake once baked.
- Baking soda
- Reacts with the sour milk to produce gas that helps the cake rise.
- Sour milk
- Its acidity activates the baking soda and adds tenderness to the crumb.
- Grated chocolate
- Gives the cake its chocolate flavour and deep colour.
The step that matters
Cooking the chocolate mixture until it thickens. If the chocolate mixture is undercooked, the egg yolk will not set and it may stay runny and thin the batter. Cooking it until thick, then cooling it, keeps the batter consistent before it is combined and baked.
