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 ↓
Brown 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the batter
Preheat your oven to 350°F (175°C).
In a bowl, beat together the brown sugar, butter, eggs, and sour milk.
Dissolve the baking soda in hot water.
Grate the chocolate.
Add the grated chocolate to the hot water with the baking soda and stir well.
Combine the chocolate mixture with the batter.
Add the flour and vanilla to the mixture.
Pour the batter into a greased cake pan.
Bake for about 30-35 minutes.
Make the filling
Boil the brown sugar, cream, and butter until it forms a string when dripped from a spoon.
Remove from heat.
Stir until cool and thick enough to spread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Adds sweetness and moisture, and helps give the cake its brown color and flavor.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Eggs
- Bind the batter and add structure as the cake sets.
- Sour milk
- Its acidity reacts with the baking soda so the cake rises, and it adds moisture.
- Baking soda
- Reacts with the acidic sour milk to produce gas that makes the cake rise.
- Flour
- Provides the structure that holds the cake together as it bakes.
The step that matters
Boiling the filling sugar mixture. The mixture must reach the right stage, forming a thread when dripped, before cooling. Too little cooking leaves a runny filling that won't set; too much makes it hard and grainy once cool.
