I'm making beef tenderloin and roasting it. Better Homes & Gardens cookbook says what temp the meat needs to be at and all. The way its worded makes me think that I leave the meat thermomater in there the entire time but this sounds wrong, and H says its wrong.
Do I leave it in the whole time or stick the thermomater in at the end of the cooking time?
It depends on your thermometer- if it's oven safe, you can leave it in the whole time, and it''ll help you gauge your timing based on how fast the roast is cooking.
oven safe one - leave it in so you're not poking the meat all the time and letting the juices spill out.
not oven safe - um.....I don't know. Don't leave it in while it cooks, but I've never used a non-oven safe one, so I'd just say good luck, and probably do what the PP suggested.
