I have a lot of Pine Trees on my Property. Is it ok to Grill and/or Smoke Over Pine? can I Smoke on Corncobs? Hickory Nuts?

In barbecue, as in life, every rule has its exception. Grill masters in parts of Germany, for example, grill bratwurst over pinecones. But in general, pine, spruce, and other resiny softwoods should be avoided for grilling and smoking. Corncobs are not only fine for smoking, in some regions they’re highly prized. Ditto for hickory nuts and shells and walnut shells.
