What each ingredient does

Cranberries
Provide the tart fruit flavour and the natural pectin that helps the preserve thicken.
Sugar
Sweetens the tart fruit and, at high concentration, helps the preserve set and keep.

The step that matters

Boil the cranberries until very soft without burning. Sugars and fruit scorch quickly on direct heat, which turns the preserve bitter and dark. Cooking gently while stirring and watching the pan keeps the flavour clean. Softening the fruit fully lets its pectin release, which the later sugar boil depends on for a good set.
