My wifes family has a TON of pecan trees on their land. Needless to say, I use a lot of pecan wood to smoke over. A few years ago I picked up a burlap sack full of pecans, took them and had them cracked, but not shelled. After sealing up the pecan halfs and putting them in the freezer, I had this brain f--t about what to do with the hulls. I thought that they might be good to grill with - like soaking wood chips to sprinkle over the hot coals in the grill. Sure enough, the next night we decided to cook some steaks on the charcoal grill. I grabbed a handfull of pecan hulls, soaked them for about an hour, and when the coals were like I like them, I sprinkled the hulls over them. Then I tossed the steaks out there and a few minutes later, we were grazing on steaks that had the BEST pecan smoke flavor!!!! My wife even commented on them. So...save the hulls!
