re: How do you do a tender pot roast...

Lot of ways to do this well. I usually braise in liquid about 3/4 up the side of the roast in a 350 oven using a covered pot. You could do this on the stove but it will take longer. Make sure to brown the roast first and use lots of trinity, heavy on the garlic. I always add some chicken base and beer to the cooking liquid.

Pressure cooker, slow cooker, and starting on the smoker and finishing any of these ways works well. Very forgiving dish, just watch the salt as it will concentrate as you go.
