Homemade Nut Butter

I’ve a wild addiction to nut butters, to the point were I've polish a kilo tub off in a week. So I thought it was about time I made my own. In our house we always have leftover nuts from recipes so it's the perfect way to use them up. I used walnuts but you could use any nuts you prefer, that goes for mixing and matching as well. So really you could create the perfect new nut butter flavour.
