Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Confectioner's sugar
- Dissolves into the cream and provides sweetness and body as the frosting thickens.
- Cream
- Supplies moisture that reduces as it boils, giving the frosting a smooth, thick texture.
- Bitter chocolate
- Adds deep, bitter chocolate flavor that balances the sweetness of the sugar.
- Vanilla
- Adds aroma that rounds out the chocolate and sugar flavors.
The step that matters
Boil the confectioner's sugar and cream until thick. As the mixture boils, water evaporates and the sugar concentrates, which thickens it. Stopping too early leaves it runny, while boiling too long can make it stiff or grainy as it cools.
