Stumbled upon this thread over on Smoking Meat Forums where they talk about using Corn Cob pellets for smoking:
In terms of flavor it sounds like they work well and could be really interesting, but this user specifies the Amazen pellet smoking device, so they are only being used for smoke, not heat. I haven't been able to find any reference to using them in a pellet grill. Has anyone used corn cob pellets in a pellet grill, and what was your experience?
