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
- Brown sugar
- Provides sweetness and the molasses flavor that defines the frosting.
- Egg whites
- Whipped to foam, they give the frosting its light, airy structure.
The step that matters
Pouring the hot syrup into the egg whites. The syrup must be hot enough to cook the whites and set the frosting, and it should be poured slowly while stirring so the foam does not collapse. Spreading it quickly matters because the frosting thickens as it cools.
