What each ingredient does

Iceland moss
Its natural gums thicken the liquid as it boils and then set into a jelly on cooling.

The step that matters

Boil the moss until it has released its gum. Iceland moss must simmer long enough for its gums to dissolve into the liquid; too little boiling leaves it thin, and it only sets properly once the strained liquid cools.

“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
