Rich and Strange Aeons

A few weeks ago, Safeway had a couple kinds of marinated pork tenderloin on sale. One of which had a very old sell-by date and was extremely squishy in its sealed plastic tube, which I managed to return before I opened it. The ones I did take home had different cooking instructions -- 350 F, or 425 F for less time -- but both came out pretty well.

Then, a few days ago, it had non-marinated tenderloin on sale. I bought one. Instruction said to cook in the oven at 425 F, 30 minutes per pound. I gave it like 45 minutes, despite being 2.3 pounds. It seemed... quite thoroughly cooked. In fact, all the interesting liquid had escaped into the cooking pan, and the meat is rather bland and dry.

Going by one allrecipies recipe, I may have massively overcooked it. Oh well.
