I use home-made pistachio butter because the store-bought one is difficult to find and expensive. I use this simple recipe from The Healthy Maven: http://www.thehealthymaven.com/2013/10/homemade-pistachio-butter.html
For the berries, I recommend raspberries, blackberries or/and red currants. —MarieGlobetrotter
