I always have a couple of 5 gallon buckets full under my smokers. Be careful though....... the nut's meat when burned makes the smoke bitter. so try and pick out the pieces. Also look for a heavy plastic bucket with a lid to keep them in, they draw rats, mice, and squirrels like crazy!
I always throw some in the pit while grilling, they work great in the chip tray on a MES, as well as the cold smoker. You can use the foil snake trick with them also an old tin can with holes punched in the bottom.
I have not tryed grinding them.
