Hi James,
Yes I do put wood in to add smoke flavour. To date I have used Oak with beef and lamb and Cherry, Apple and Pear with pork and chicken. I tend to put at least two chunks of wood (I don't use chips) on the side of the basket nearest the air inlet at the bottom of the barrel as I find the fire tends to burn from that point to the other side of the barrel consistently.
To put the coals out I take the basket out of the barrel and put it on top of my Weber kettle and close the lid with all vents closed. This does kill the fire and saves coals for the next cook as I very rarely end up using the entire basket full. I guess you could do the same by covering all the inlets top and bottom on the barrel but personally I have never found anything big enough to close over the bottom inlet and I suspect it would still take longer to kill the fire in the PCB than it does on my Weber. By the way I did invest in a number of magnet hooks from Amazon which are big enough to cover the hanging bar holes at the top of the OCB when I want to lower the temp but yiu could do the same with balls of foils place in the holes.
Hi Sotv,
Yes I have hung baby back ribs and have not had any issue with meat falling off the hooks as yet. In addition I hung short ribs, pork belly, pork butt, leg of lamb, shoulder of lamb, brisket and never had an issue. Now that I've jinxed myself the next cook will probably end up in the coals. Having said that I am very careful with the hook placement and if am in any doubt will use two hooks, either daisy chained (ie. so one hook is over the bar and the second hook is hanging from the first) or separately hooked over both rods. It is inevitable that something will fall off the hook at some point I guess.
In learning to use the PCB I watched a lot of videos from the PCB company and others to see how they did things. I also use the PCB for cold smoking with my ProQ maze when I have larger pieces of meat or fish I want to smoke.
