What each ingredient does

Gooseberries
Provide the fruit, pectin and tartness that form the base of the jam.
Preserving sugar
Sweetens the fruit and helps the jam set and keep well.
Cold water
Starts the fruit softening and dissolves the sugar as the mixture heats.

The step that matters

Testing the set on a cold plate. Jam sets as its pectin and sugar concentrate during boiling. A cold-plate test shows whether the syrup will gel, so the jam is not overcooked or left runny.
