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 slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the chocolate mixture
Melt the chocolate with ⅓ cup sugar, ¾ cup milk, vanilla, and beaten egg yolk in a bowl over a tea kettle until smooth.
Make the batter
In another bowl, cream the butter with ½ cup sugar.
Add ⅓ cup milk, 1 egg, baking soda, and flour to the butter mixture.
Combine the chocolate mixture with the batter, adding a little more flour if needed.
Mix well and pour into a greased baking pan.
Bake
Bake in a cool oven at 300°F (150°C) until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air and give the cake a tender, rich crumb.
- All-purpose flour
- Provides the structure that holds the cake together as it bakes.
- Egg
- Binds the batter and helps set the crumb as it bakes.
- Egg yolk
- Adds richness and emulsifies the chocolate mixture for a smooth texture.
- Baking soda
- Reacts with the batter to produce gas that helps the cake rise.
- Chocolate
- Supplies the chocolate flavor and deep color of the cake.
The step that matters
Melting the chocolate mixture gently. Chocolate can seize or turn grainy if overheated. Melting it slowly over gentle heat keeps it smooth so it blends evenly into the batter.
