Why it works: Egg and sugar are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Common Frosting
Ingredients
Directions
Make the frosting
Beat the egg whites in a bowl until frothy but not stiff.
Add the sugar and water, then mix well.
Place the bowl over a boiling kettle and stir until the mixture thickens to a waxy consistency.
Remove from heat and stir in the air until partially cool.
Spread on the cake
Use a clean knife dipped in cold water to spread the frosting on the cake while it's still warm for better adherence.

What each ingredient does
- Egg whites
- Whipped into a foam and heated, their proteins set to give the frosting body and structure.
- Granulated sugar
- Adds sweetness and dissolves into the whites, helping the frosting thicken to a smooth, glossy texture.
The step that matters
Thickening over the boiling kettle. Heat sets the egg white proteins and thickens the mixture. Stop once it turns waxy, because overheating can scramble the whites and leave a grainy texture, while too little heat leaves the frosting runny.
