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 custard
In a saucepan, combine grated chocolate, ½ cup sweet milk, ⅔ cup brown sugar, and egg yolk. Boil until thick like custard, then cool.
Make the batter
In a mixing bowl, cream together ½ cup butter and 1 cup brown sugar.
Add ½ cup sweet milk and 2 eggs to the butter mixture, then mix well.
Stir in the cooled custard mixture.
Dissolve 1 teaspoon baking soda in a little boiling water and add to the batter.
Flavor with 1 teaspoon vanilla and mix until smooth.
Bake
Pour the batter into a greased baking pan and 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
- Eggs
- Add structure and moisture, and enrich the batter so it sets as it bakes.
- Butter
- Adds fat that makes the crumb tender and rich.
- Flour
- Forms the structure that holds the cake's shape as it sets.
- Baking soda
- Releases gas in the batter, helping the cake rise.
- Brown sugar
- Sweetens the cake and adds moisture and a deeper flavor.
- Grated chocolate
- Gives the cake its chocolate flavor, color, and richness.
The step that matters
Boil the custard until thick, then cool it. The egg yolk thickens the chocolate mixture as it heats, but high heat can curdle or scramble it. Cooking gently while stirring gives a smooth custard, and cooling it before adding it to the batter keeps the batter from being overheated.
