What each ingredient does

Fresh raspberries
Provide the main flavour and colour, and the juice that forms the jelly.
Isinglass
Sets the liquid into a jelly as it cools.
Sifted sugar
Sweetens the jelly and helps draw juice from the crushed raspberries.

The step that matters

Stirring in the isinglass. Isinglass must be melted and cold enough to mix in evenly without clumping, and the juice should be well strained so the jelly sets clear and smooth.
