Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base that melts the chocolate and makes the icing pourable.
- Good chocolate
- Provides the main flavor and, as it cools, firms the icing for a glossy finish.
- Powdered sugar
- Adds sweetness and body, thickening the icing as it dissolves.
- Egg white
- Adds lightness and a smoother, airier texture when beaten and folded into the warm mixture.
The step that matters
Pour the mixture over the egg white. The warm chocolate mixture can partly cook the beaten egg white and cause lumps. Pouring slowly while mixing blends them evenly and keeps the icing smooth.
