Why it works: Sugar and egg 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 ↓

What each ingredient does
- Sugar
- Sweetens the frosting and, once boiled into syrup, sets the soft, glossy structure.
- Egg white
- Whipped with the hot syrup to form a light, airy foam that gives the frosting its volume.
The step that matters
Pouring the syrup onto the egg white while beating. Pouring the hot syrup slowly while beating constantly lets it cook the egg white gradually into a stable foam. Pouring too fast or stopping to beat can deflate the mixture or leave it lumpy.
