Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Adds richness and body to the chocolate base, helping it feel smooth and creamy.
- Egg white
- Whipped to a light foam that sits on top and gives the drink a light, airy texture.
- Melted chocolate
- Provides the chocolate flavor and some richness to the base.
- Milk
- Makes up the liquid body of the base and adds creaminess.
The step that matters
Beat the egg white until light and fluffy. Egg white needs to be whipped to a light foam to hold its volume on top of the drink. Under-whipped white stays flat and runny, while over-whipped white turns dry and grainy.
