So its been a week since I got my Oklahoma Joe Highland First time smoking I used Kingsford briquettes 15.40 at 8.94 burned for 12 hours full bag at 225-245 without baffle no fire box, had to keep feeding fire didn't take long to heat up guessing on that because i smoked ribs with 3 mesquite chunks plus the first burn that day Second time was Royal Oak lump coal 16.6lb at 11.36 burned 4 hours, full bag 225-245 with baffle and fire box Third time was just the Walmart grill charcoal briquettes 16.6lb at 5.97 burned half a bag with 1 cherry chucks at 250-275 (for chicken) 5 hours with baffle fire box with minion method took 1 hour and 45 minutes to come up to temp, had air intake almost all the way open Am I doing something wrong here? that last burn was insanely long to get to temp. with the minion method, didn't work great in the fact it didn't really burn one part then another, I have to fix the basket fire got under the plate and burnt coals next to it. Kinsford made a ton of ash i cleaned under grate at the time 4-5 times Royal oak cleaned under charcoal box 3 times Walmart's brand I only cleaned twice I want to do a brisket soon and at these times I'm going to need a ton of fuel unless I can get more use from it. Any suggestions?
