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 batter
Cook the milk, egg yolk, and chocolate together like a custard.
Cream the sugar and butter together.
Add the custard to the creamed mixture.
Dissolve the baking soda in ½ cup of milk and add it to the mixture.
Stir in the flour and vanilla until well combined.
Bake and frost
Pour the batter into a loaf pan and bake at 350°F (175°C).
Use the egg white to make frosting once the cake is baked.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the main structure that holds the cake together as it bakes.
- Egg yolk
- Adds richness and helps bind the custard, giving the crumb tenderness.
- Baking soda
- Reacts with the milk to produce gas that lifts and aerates the batter.
- Sugar
- Sweetens the cake and helps tenderize the crumb when creamed with butter.
- Butter
- Adds fat for moisture and a tender texture.
- Chocolate
- Provides the chocolate flavor and some fat that deepens the cake's color.
The step that matters
Cook the milk, egg yolk, and chocolate as a custard. Egg yolk thickens when heated gently, but too much heat can scramble it into lumps. Stirring steadily over low heat keeps the custard smooth so it blends evenly into the batter.
