Does anyone have any wood recommendations?
Chuck,
I presume you're asking for recommendations of what kind of wood to burn in the oven.
Hardwoods like oak, hickory, and pecan are a good choice. Mesquite burns very hot, but the smoke is quite acrid and may be too strong unless you stick to mesquite charcoal (lump, not processed).
For health and safety (to say nothing of taste) reasons, stay away from soft, resinous woods like pine and cedar. (A byproduct of combustion of the resin is creosote. which is not only highly flammable, but potentially carcinogenic.)
Also, it's generally not a good idea to use waste wood (building scraps, wood pallets,
etc.) unless you know with absolute certainty that it's raw (untreated) wood. The most common weather-treating compounds contain aliphatic petroleum distillates, which have been labelled carcinogens, and/or arsenic.
