What each ingredient does

Iceland moss
Its natural polysaccharides thicken and set the water into a jelly as it boils.
White sugar
Adds sweetness and balances the mild, earthy flavour of the moss.

The step that matters

Boil the moss until very thick. The moss must be boiled long enough for its gel-forming polysaccharides to dissolve and thicken the liquid. Stopping early leaves a runny result, and the thickened liquid should be strained while it is still hot.
