I've seen many recipes where the temp to cook at is anywhere from 325 to 400 degrees. Which also changes how long to bake in the oven. The tenderloins I have total approx 2 lbs. What oven temp produces tasty pork without drying out the meat. Also, according to the many recipes, the temps varying on what to cook the meat to...145, 150, etc. I do have an instant read thermometer. Please advise. Thanks.
