So, I've been lighting using the minion method (lump the last few times though if it matters) and will place 3 small chunks of wood along the outside of the ring in my 18.5" WSM buried about halfway down. Once the WSM hits 225 I will throw another chunk on in the middle where I dumped the small amount of lit coals and put the meat on. Problem is I get billowy white smoke like this. It seems like if I don't put the chunk in the middle then I get no smoke even though I'm at temp (at least until well into the smoke when the outer chunks of charcoal have lit). What am I doing wrong as far as setting my wood up to get the thin blue smoke from the start?
