My PK (Portable Kitchen) I bought in the early 70s a cast aluminum with one vent on the top then two vents in the bottom. Still works very well but had to buy a charcoal grate and a cooking grid.
When I cooked poultry I used charcoal with hickory or pecan. Then I used for steaks with plain charcoal and some times mesquite. The last time I used some apple chips in Cornish Hens. That turned out very well...and no one complained eating them.
Any one used or favorite the type wood chips or pellets?
