I like mesquite wood best for smoking. I start with a bunch of regular wood logs, like the kind you buy at Home Depot for your fireplace. Once I have a really nice bed of coals, I start putting chunks of mesquite wood on the coals. You have to do this about every fifteen minutes in order to keep the smoker going. I've smoked pork ribs, country ribs, brisket, pork loin, corn on the cob and even managed to make a good smoked salmon. (Great for breakfast with onions in eggs.)
I have some other things in mind a want to try, like smoking a lasagne or stuffed eggplant. My doctor keeps yelling at me about my cholestorol and stuff like that, but I can't help it! Texas Monthly has a great article on the Best Barbecue Joints in Texas. I was drooling after the first page!
How does this relate to writing? When you smoke, be prepared to spend six to eight hours just tending the smoker. This allows you to relax in the backyard and think, read or write. It a very relaxing way to spend the day, not to mention all the food you get to eat when you're done!
