POT ROAST Rule of Thumb:
The pot roasts we have included in our cookbook vary on cooking time and temperatures. It all depends on the amount of liquid (onions are an added source), the pot they are in, and your oven. Many old recipes had temperatures as high as 450º. This could be due to types of ovens, or a variety of things. Our Rule of Thumb is to check for liquid and doneness, once you pass the 1 hour time mark. You don't want it to dry out, BUT you DO want it to be fork tender and to fall of the bone, so to speak. "Keep you eye on your Thyme!"

If you love the flavor of mushrooms, this pot roast is for you.
Pancetta is “Italian bacon” and can be found in the deli section of the supermarket.
Serve over premade polenta, found in chubs in the supermarket.

I think it was Jennifer who found this in a magazine.
We tried it and fell in love. The polenta was delicious with it.
