I wanted to make this because of the mustard and pepper rub down and it was surely worth it. I used carrots because the butternut just would not have flown in this house and the wee bite size Yukons were the only spuds I had . They both worked perfectly to make a happy dinner time. I didn't weigh the roast when I took it out of the freezer this morning but I know that it was close to 2 lbs. Using the times given it came out with well done ends for DH and a med rare center for me, ideal! I really loved that mustard and pepper combo but I used a grainy Dijon and I think that it would work better with a smooth Dijon and I'll use that next time. The gravy tastes great too.
