Method

•  Place the cream, zest and sugar into a deep medium pot
• Gently bring to the boil, stirring constantly to dissolve the sugar
• Once it has come to the boil continue for a further 3 minutes so the mixture thickens slightly
• Do watch this stage constantly as it has a tendency to boil over! Remove from heat and add 1 Tbsp orange juice
• Stir to combine and cool slightly
• Pour into decorative, individual glasses, or one large dish
• Allow at least 3 hours or overnight to set
• Meanwhile, place the fresh blackberries and icing sugar in a bowl, squeeze over remaining orange juice and let the berries macerate for at least 30 minutes to 1 hour
• This allows the natural juices to flow
• Serve when set with the berries generously spooned over the top (juice as well)
