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
- White sugar
- Provides sweetness and, once boiled, the hard candy structure of the filling.
- Egg whites
- Beaten into foam, they add airy structure and a light, fluffy texture.
- Citric acid
- Adds sharp acidity that balances the sweetness.
The step that matters
Boil the sugar to brittle candy. The sugar's final texture depends on how far it is cooked. Too little leaves it soft and sticky, while too much makes it hard and bitter. The cold water test shows when it has reached the brittle stage.
