What each ingredient does

Cornstarch
Thickens the juice into a smooth sauce when heated and boiled.
Sugar
Adds sweetness and balances the tartness of the juice and lemon.
Lemon juice
Adds acidity that brightens the flavour of the fruit juice.
Fruit juice
Provides the main fruit flavour and liquid base of the sauce.

The step that matters

Boil the sauce while stirring constantly. Cornstarch only thickens fully once it reaches a boil. Stirring keeps the starch evenly dispersed so it does not clump or scorch on the bottom of the pan.
