This is a surprising simple and easy to make recipe that produces a fantastic dessert. The main time taken here is waiting for the pastry to chill and then rolling it out.
The dark chocolate flavour is offset by the double cream, orange zest and orange juice. Throw in a splash of Cointreau and you have an intensely rich dark chocolate tart balanced by the sweet orange flavour. This tart brings back memories of crunching on Jaffa lollies.
Serve with whipped cream or ice-cream and you have a wonderful decadent dessert. You can substitute the dark chocolate for milk chocolate, but I think that would take away some of the rich intensity the dark chocolate creates.
