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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the custard as they set when heated, giving it body.
- Milk
- Forms the liquid base that the chocolate and eggs are combined into.
- Vanilla chocolate
- Provides the chocolate flavour and colour, and melts smoothly into the hot milk.
The step that matters
Adding the eggs to the boiling chocolate. Egg proteins set when they meet high heat, so they can curdle into lumps if added too fast or without stirring. Stirring well while adding them keeps the custard smooth.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
