Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

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 batter
Combine egg yolks, ¼ cup milk, and melted chocolate in a saucepan. Cook over low heat until smooth.
Remove from heat and add the remaining ingredients, mixing well.
Bake
Pour batter into a greased baking pan.
Bake in a slow oven at 300°F (150°C) until a toothpick inserted in the center comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Add richness and help bind the batter, giving the cake structure and a tender crumb.
- Sugar
- Adds sweetness and helps keep the cake moist and tender.
- Baker's chocolate
- Provides the chocolate flavor and deep color of the cake.
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Baking soda
- Reacts with the batter to produce gas, helping the cake rise and lighten.
- Butter
- Adds fat for moisture, tenderness and richness in the crumb.
The step that matters
Cooking the chocolate, egg yolk and milk mixture. Cooking over low heat gently thickens the egg yolks and smooths the melted chocolate without scrambling the eggs. Heating too fast can curdle the yolks, leaving lumps that will not blend into the batter.
