Today I did a 4 hr at 275* for a 3.75 lb St. Louis rack of spares. This rack was a little larger than my usual St. Louis cooks and some of the riblets were still attached on the shorter ribs. I prepped with mustard, then Meat Church Honey Rub. Previousy I confirmed that the 1070 with Offset at +7 gave almost precise temps at both 225* and 275* and that doing St.Louis spare for 4 hrs at 275* without wrap or sprits results in drier ribs than we like. So I modified by spritzing with ACV/H2O at 2hrs and 2.5 hrs. Then at 3 hrs. wrapped in foil with just ACV/H2O about 2 oz and meat side down and back in at 275* for 45 minutes. Then painted them and back in smoker naked for about 20 minutes. So altogether, the cook was 4 hrs 5 minutes . They were as near perfect as I have done at any temp and pulled off the bone with ease. Only pics I took follows:
1. Smoker at 275* smoked well almost the entire cook.
2. Prepped and ready to go into 1070
3. Painted and pulled, ready to cut. Had nice smoke ring.
While wrapping takes more effort, I streamlined the effort by eliminating the brown sugar, honey, butter, Tiger sauce and just added a little moisture in the foil. The end product did not disappoint, as they were moist and tender with a nice bark. I think that either this way or salt and pepper will do it for us.
After much testing I finally disagree with RT that the factory setting of Offset at 0 provides overall correct temps that match the set temp. I have tested mainly at 225* and 275* multiple probes and in as many as 18 positions (9 on upper and 9 on lower grates) and took many hours to do so. And the results when retested, were reproducible. Those are the only temps I am concerned about for low/slow accuracy. Also, have confirmed that on "full" I can reach 700*. I think RT is the only control that can be adjusted by the consumer for accuracy. ?? When I had the 590, it was adjusted to +6 on Offset and was really accurate as well. Why RT provides this adjustability, makes a video on how to make the adjustment and then advises not to use it is beyond me..
