What each ingredient does

Fine ripe damsons
Provide the fruit juice, along with natural pectin and tart acidity that help the jelly set.
Good sugar
Sweetens the jelly and, at high concentration, helps it set and keep its shape.

The step that matters

Boil quickly after adding the sugar. Sugar must dissolve fully before a hard boil, and the mixture must reach a rolling boil for the set to form. Constant stirring prevents sticking and scorching on the base of the pan.
