What each ingredient does

Arrowroot
Thickens the liquid into a clear, smooth jelly as it heats and gels.
Sugar
Sweetens the jelly and balances its mild flavour.
Cold water
Forms the liquid base that the arrowroot thickens.

The step that matters

Stir constantly and boil for 3 minutes once it starts boiling. Arrowroot must be stirred as it heats so it does not clump, and it needs to reach a boil to thicken fully. Stopping the stirring or boiling too little can leave the jelly thin or lumpy.
