Dear Polly: I would appreciate knowing what is considered to be a simmering temperature in an oven? I prefer to cook soups in ovens rather than on top of the stove because they don't burn as easily on the bottom. - C.S.
I have excellent results cooking pot roasts in the oven at 225 to 250 degrees. The result is a very tender, flavorful pot roast. Soups and meat stocks can be cooked at the same temperature. Of course, since ovens vary greatly in their temperature accuracy, monitor the pot to find the optimum oven setting in your own oven. The liquid should bubble very gently.
