What each ingredient does

Iceland moss
Provides the gelling agent that thickens the water into a jelly as it cooks.
Cold water
Soaks and extracts the moss's gelling compounds, then forms the body of the jelly.
White granulated sugar
Adds sweetness and balances the mild, earthy flavour of the jelly.

The step that matters

Boil for 20 minutes, stirring constantly. Once sugar is added, the jelly must boil long enough to set properly. Constant stirring prevents scorching on the base of the pan, where the thickened mixture can burn quickly.
