Soak the dates is warm water for 30 minutes and then roughly chop them.
Add the dates and pistachios to a food processor and blitz for about 1 minute.
Divide the nut and date mixture into 4, spread onto the bottom of 4 glasses or dessert dishes.
Over the nut mixture spread 2 teaspoons of lemon curd as evenly as you can, top with a layer of raspberries.
Give the yogurt a good stir so it almost looks like whipped cream then divide it into 4 and pour over the raspberries, you could refrigerate for 30 minutes at this stage if you wish it to be colder or if you are making in advance, this very rarely happens in my house!
Top with some shavings of dark chocolate.
