10 Mar 2014 I recently bought a food processor and started experimenting with homemade nut butters. Since I grew up on Nutella, I decided to try and make a chocolate-hazelnut butter. Unfortunately, I accidentally bought raw rather than roasted hazelnuts. Nut butters (peanut butter, almond butter...) are made from roasted, not raw nuts. Before processing into a nut butter, the nut should be roasted. The process of roasting hazelnuts is fairly simple.
