What each ingredient does

Gooseberries: Provide the fruit pulp and the tart flavour that defines the jelly.
Castor sugar: Sweetens the tart gooseberries and balances their acidity.
Leaf gelatine: Sets the strained purée into a firm jelly that holds its shape.
Lemon rind: Adds a bright citrus aroma that lifts the gooseberry flavour.

The step that matters

Dissolving the gelatine. Gelatine only sets when fully dissolved and evenly mixed through the purée. Any undissolved grains or lumps leave weak, uneven patches in the finished jelly, so strain the dissolved gelatine into the mixture before pouring it into the mould.
