What each ingredient does

Fruit (apples or crabapples)
Provides pectin, acids and the main flavour once mashed into a smooth pulp.
Granulated sugar
Sweetens the jam and, at high concentration, helps preserve it and form a crust.

The step that matters

Stirring until the sugar fully dissolves. Undissolved sugar crystals can remain in the jam and seed later crystallisation. Stirring steadily for the full time gives a smooth, evenly sweet result.
