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
- Granulated sugar
- Dissolved and boiled into a syrup that sets the frosting's sweetness and structure.
- Egg whites
- Whipped into a foam that gives the frosting its light, airy body.
- Marshmallows
- Melt into the warm foam, adding sweetness and a soft, stabilising texture.
The step that matters
Pouring the syrup while beating. Hot syrup must be poured in a thin stream while beating constantly so it cooks the egg white foam smoothly rather than scrambling it. Beating until cool keeps the foam glossy and spreadable.
