The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Sugar
- Provides sweetness and, when cooked, the syrup structure that sets the marshmallow.
- Glucose
- Inhibits sugar crystallization, keeping the texture smooth and soft rather than grainy.
- Gelatin
- Forms a flexible gel network that traps air and gives the marshmallow its elastic body.
- Frappe powder
- Stabilizes the whipped foam, helping it hold air and stay light and fluffy.
The step that matters
Adding the gelatin off the heat. Gelatin is damaged by high heat, so it should be added only after the syrup is removed from the burner. Adding it while the syrup is still boiling can weaken its gelling power and leave the marshmallow limp.
