I fired up my WSM with the minion method and lump charcoal from Costco on Thurs. nite at 7:00 pm. Started 2 pork butts & a brisket. Got to 225 degrees and held through the night. At 8:30 am in the morning food was perfect and temp was still 218, even with a rain shower. Decided to smoke 3 racks of babybacks on same coals. Didn't add any, just stirred the coals before I put ribs on. 6 1/2 hrs later my ribs were perfect and the temp was holding at 233. This is only my 2nd smoke on the WSM. Wow!! Either this thing's incredible or lump charcoal is as good as advertised... OR both
