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
- Dissolved in water and boiled, it forms the syrup that sweetens and sets the frosting.
- Egg white
- Whipped into a foam that gives the frosting its light, airy structure.
The step that matters
Slowly add the syrup to the beaten egg white. Hot syrup poured in too quickly can deflate the whipped foam or cook the egg white unevenly. Adding it in a thin, steady stream while beating keeps the foam stable and the frosting smooth.
