Did my first ever this year due to the $7/# deal at Safeway.
Small 3 bone just for the 2 of us.
Perused here and recipe sites and used what I had (coarse black pepper, coarse kosher salt, garlic powder, rosemary, thyme and Mansmith's Rib Rub). Sit for a couple hours at room temp.
Slow roasted (225*) in oven until internal reached 125-130 (we are not a rare/medium rare family). Let it rest (tented) while a side went in the oven for 30 minutes, cranked the oven to 500* and "seared" for 10 minutes. Set for another 20 minutes while making another side before slicing.
No complaints.
