Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Provides the liquid that melts the chocolate and dissolves the sugar into a smooth mixture.
- Good chocolate
- Supplies fat and rich flavor, and sets as the icing cools.
- Powdered sugar
- Adds sweetness and body, and dissolves into the warm liquid for a smooth texture.
- Egg white
- Adds structure and a lighter body when whisked into the icing.
The step that matters
Pour the mixture over the egg white. The chocolate mixture is hot, and heat cooks egg white proteins, so it can scramble or turn grainy. Pouring slowly while beating gradually warms the egg white and keeps the icing smooth.
