What each ingredient does

Isinglass
Gelatin-like protein that sets the water into a firm, wobbly jelly as it cools.
Water
Dissolves the isinglass and forms the body of the jelly.

The step that matters

Boiling the isinglass until firm. Isinglass must be fully dissolved by boiling so it can set evenly when cooled. If it is not fully dissolved, the jelly may set unevenly or stay soft in places.
