I have smoked ribs about four times in the last couple years. I’ve been fortunate enough to have my father’s MasterBuilt smoker. It is a box about the size of a dorm fridge, and can readily smoke two racks, each…

RIMU Calibration
I turned the freezer up to 7. I’m sure yours goes to 11, but I am not so lucky. After being turned up to 7, the resulting mean temperature is still too high at 18.8°F. And with that, we bid…
