This recipe is by Don Mauer, a syndicated food columnist. The technique used here makes for a fast yet tender pot roast. The 90 minutes refers to time in the oven, there is additional time needed for brining and cooking. Do not cook vegetables with the pot roast - cook them separately or parboil and add to the gravy as it cooks. Prep times are estimated, as I have not made this yet, but am looking forward to doing so. Please note that the sodium count is off - the sodium is principally in the brine, which is discarded.
