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 mixture
Grate the baker's chocolate and mix it with ½ cup of milk.
Add the egg yolk, 1 cup of sugar, and 1 teaspoon of vanilla.
Boil until dissolved.
Let the mixture cool.
Make the batter
In a separate bowl, cream together ½ cup of butter and 1 cup of sugar.
Add ½ cup of milk, 2 cups of flour, 2 teaspoons of baking powder, and 2 eggs to the butter mixture.
Stir in the cooled chocolate mixture.
Bake and assemble
Pour the batter into jelly‑cake pans.
Bake at 350°F (175°C) until done.
Once cooled, put icing between the layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Baker's chocolate
- Gives the cake its chocolate flavor and color.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Sugar
- Sweetens the cake and helps give it a tender texture and browning.
The step that matters
Let the chocolate mixture cool before stirring it into the batter. If the hot chocolate mixture goes into the creamed butter and sugar, it can melt the butter and loosen the batter, leading to a denser or greasier cake. Cooling keeps the batter emulsified and stable.
