What each ingredient does

Arrow-root
Thickens the boiling water into a clear jelly as its starch swells and sets when cooled.
Sugar
Sweetens the jelly and dissolves into the boiling water before the starch is added.
Lemon juice
Adds acidity that brightens the mild, sweet flavor of the jelly.

The step that matters

Stir until clear, boiling steadily all the while. Arrow-root starch must be fully heated and kept boiling while stirred so the granules swell and cook evenly. Stopping early or letting it sit leaves the jelly cloudy, lumpy, or unable to set firmly.
