Orange Jelly

Pour the boiling water into a bowl and add the Knox sparkling gelatine and sugar, stirring constantly until both are fully dissolved, approximately 2 minutes.

Add the orange juice, cold water, and lemon juice to the gelatine mixture, stirring well to combine all ingredients evenly.

Pour the mixture into a jelly mold or shallow serving dish, distributing evenly.

Refrigerate the jelly for at least 3-4 hours, or until firmly set and no longer wobbles when gently shaken.

Turn the jelly out onto a serving plate by dipping the mold briefly in hot water and inverting onto the plate, or serve directly from the dish cut into portions with a wet knife.
