Why it works: Gelatin and sugar are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,778 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

What each ingredient does
- Gelatin
- Forms the elastic gel network that gives marshmallow its firm, springy structure once cooled.
- Sugar
- Provides sweetness and, dissolved in boiling water, forms the syrup that sets into the body of the candy.
- Water
- Dissolves the sugar and hydrates the gelatin so it can set evenly.
The step that matters
Whisk the mixture until very stiff. Whisking traps air bubbles in the hot gelatin-sugar syrup, creating the foam that gives marshmallow its light texture. Whisking too little leaves it dense, and it must be beaten until it holds its shape as it cools.
