What each ingredient does

Iceland moss
Its natural gums thicken the water as it boils, setting it into a jelly.
Powdered loaf sugar
Adds sweetness to the finished jelly.

The step that matters

Boil for 1 hour, stirring frequently. The moss must simmer long enough for its gums to dissolve fully into the water. Stirring often prevents sticking and scorching on the bottom of the pan, which would give the jelly a burnt taste.
