I cooked them!
Tried something new (for me.) I heated some coconut oil in a round skillet over 2 charcoal baskets filled with, you guessed it, hot charcoal. That was my sear for a couple minutes on each side. "Montreal Steak" was the seasoning. I think I envisioned a blacker char or something being right on the cast iron but it didn't happen. Whatever. Too much oil perhaps.
My old Weber digital thermo stick initially said about 110 for each steak (cooking indirect, by now) so I walked away to do other stuff. I came back "just a second later" and it was reading like 150 wherever I stuck the needle in them. What the heck. I yanked them!
I think the meat wasn't as hot as indicated. Luckily! Freakin' tender and juicy. FREAKIN,' sez I.
