I didn't use a probe in the ribs themselves – I've been advised against that, as they're so thin and the meat is so close to the bone.
I cooked at 230-250F - and I checked that regularly.
The display on the ProQ is not 100% reliable, I gather - it was saying 200F, but my probe that I poked through the eyelet said 240F most of the time.
I guess there are so many variables:
- it was incredibly windy yesterday (and still is today), so maybe that cranked up the airflow and heated things up?
- the size/thickness of the ribs
- the outside temp
But I have a few more racks in the freezer, so I'll vary things a bit next time.
@Justin - you did ribs for 4-4.5 hrs last time, didn't you? Perhaps I'll try that (mine were on for 6 yesterday).
