Whip a 142ml carton of double cream in a large bowl with 3 tablespoons of sifted icing sugar until just beginning to thicken. Gently stir in 300g Greek yoghurt.
Break some meringues into small pieces and fold into the cream mixture. Carefully stir in a jar of Real Organic Summer Fruit Conserve leaving it just roughly mixed. Spoon into glasses and chill for at least an hour.
Serve decorated with fresh summer berries such as redcurrants or raspberries. Serves 6.
