After putting my new MES through its first smoke, I was very pleased with the results. Both BB Ribs (2-2-1) and a tri-tip came out awesome. But, when I went to clean it out a little bit and empty the chip tray, it looked like most of the wood didn't burn. There was some white ash at the bottom, but a ton of the wood looked like it just turned to charcoal and never fully burned. Since I was only smoking for about 5 hours, it wasn't too bad, but if I was going for 8 or 10 hours, I would have ran out of room in the tray. Is that normal that it all didn't totally burn to white ash? Did I do something wrong, or am I just missing something? I didn't even soak the chips because I read on here that you shouldn't soak if you're using an MES. The funny thing is that I really didn't seem to have any problem with smoke production. There seemed to be plenty of smoke, even though some of it looked whiter than it should.
