I cook mine in a cast iron dutch oven. We do lots of deer roasts and they are perfect. I put a roast in, add some water, onions, potatoes, carrots or whatever and stick it in the oven. Temperature depends on how long I have to cook it. If I'm in a hurry its 375...otherwise about 300. There is always a rich juice that makes the best gravy too. I absolutely love cooking in cast iron though!
