Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten into a stiff foam that gives the frosting its light, airy structure.
- Powdered sugar
- Dissolves into the whipped whites to add sweetness and body to the frosting.
- Cornstarch
- Stabilizes the frosting by absorbing moisture, helping it stay smooth and firm.
The step that matters
Beating the sugar into the whites. Adding the sugar gradually while beating continuously keeps the foam stable and prevents a grainy or runny frosting. Stopping early leaves lumps of undissolved sugar.
