I got this recipe from the Living magazine. It is really good and easy to make.

1/4 cup pistachios
1 tbsp sugar
pinch Kosher Salt
1/8 tsp orange blossom water
1 tsp vegetable oil
8 large Medjool dates, cut lengthwise
1/3 cup dark chocolate (melted) – optional

Pulse the pistachios, sugar, salt and orange water together in a food processor until it becomes a fine paste. Add in oil, half teaspoon at a time, to achieve a butter like texture. Fill each hollow date half with pistachio paste splitting it evenly between the date halves. Drizzle the dark chocolate over the dates and let stand until chocolate sets. About 15 minutes. The original recipe calls for adding a small sliver of candied orange peel to these, which would be a wonderful addition, but we like them without as well.
