So wife had two 1 1/2 lb pork loin roast. It is packaged in its own onion & garlic marinade. I know I had some people tell me to only cook it to 145 IT since they tend to dry out. what temp should I have it at 200°, 225°,or 250°. How long do yall think it would take? 2hrs? I wanted to try and make them for lunch tomorrow b4 the wife goes into work at 12:30.
