What each ingredient does

Tapioca
Starch that thickens as it cooks and turns the liquid clear and jelly-like.
Lemon juice
Adds acidity that brightens the flavor and balances the sweetness.

The step that matters

Simmer until clear. Tapioca starch thickens and turns transparent as its granules swell and gelatinize with heat. Stopping too early leaves the jelly cloudy and loose, while stirring often prevents scorching on the bottom of the pan.
