As I said, pumpkin seeds and sunflower seeds can sichhervorragend crush. I'm in my Müssli always pumpkin seeds and sunflower seeds hinnein, but they do not want to chew. They can be in this mill crush almost to flour and give the Müssli a great aftertaste. Tastes almost like marzipan and pistachio. :) The whole can be swept with a small brush wonderfully from the mill. Excellent!
