Well I decided that I either had to freeze or cook the 2 4.75 pound shoulder roasts I had in the fridge so I jumped in with my second cook ever on my WSM and the first using a clay saucer.
I followed the instructions on this site for and did the Minion method with 40 briquets (its cold'ish tonight but not windy) and within 5 minutes had to take the 3 bottom vents down to about 10% if that. Temperature hovered right around 252 for awhile and then has been slowly climbing for the past 2 hours.
About 45 min or so ago I shut down all the 3 bottom vents and the temp climbed from about 261 to 271. Within Chris's recommended 25 degree range but higher than I'd like.
I'm concerned about running it all night with the bottom vents 100% closed and that the fire might die out (even though it continues to climb slowly now).
What should I do? Open them ever so slightly open or run them closed all night?
As an FYI I'm using a maverick ET-73 and with the smoker probe I'm just hanging it inside the top most vent with the part where the probe ends and the fabric/mesh begins sitting on the lip.
Any ideas? Anyone awake still?
