So I pulled out the 2 racks that were in the longest about 2:15 til just after 7. They looked done and the piece I tried on the end was very tasty.
I brought these over to my parents house for dinner and when I cut them apart I found they were medium to medium rare at best. We put them in the oven at 350 wrapped in foil for over an hour, they are well done now, but are still not tender, so those 2 racks are still in the oven at my parents.
Now I have 3 racks still in the smoker, we just checked them after another 1.5 hours and they are fairly tough / leathery.
My feeling as to what happened here is that I really set myself back a lot when i had to open the smoker to add the 2nd ribs that I didn't have thawed in time. It's only 18 degrees here tonight.
For both the wrapped ribs in the oven currently and the unwrapped ribs in the smoker, will they both get more tender if I give them more time?
Thank You,
Jamie
