What each ingredient does

Strawberries
Provide the fruit flavour and the juice that forms the body of the jelly.
Sugar
Adds sweetness and helps the jelly set firm when boiled.
Isinglass
Acts as a gelling agent that sets the juice into a jelly as it cools.

The step that matters

Boiling to jelly consistency. Boiling concentrates the sugar and juice until the mixture reaches the point where it will set. Boiling too briefly leaves it runny, while boiling too long can make it stiff and dull in flavour.
