This sounds really interesting. DH would kill me if i did it!

Sorry I havent read through the full thread, but in reference to the peanut butter that Bath's DH wanted.

The health food store I worked at at uni had a machine that made nut butters. Customer could bring in their own nuts (macadamia, peanuts, hazelnuts etc) and they would put them through the machine and make it in to nut butter - much better than that stuff at the supermarket.
Maybe there is somewhere near you that does the same thing.
