Why it works: Milk and butter 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate
- Provides the main flavor and the body of the paste.
- Egg
- Its proteins set with heat, helping the mixture thicken.
- Sugar
- Adds sweetness and balances the bitterness of the chocolate.
- Butter
- Adds richness and a smooth, glossy texture.
- Milk
- Thins the melted chocolate and adds creaminess.
The step that matters
Continue to cook, stirring frequently, until the mixture thickens. Once the egg is in, the mixture can scorch on the bottom or curdle if it gets too hot. Frequent stirring spreads the heat evenly, and the egg proteins set gradually into a smooth, thick paste.
