This was prepared on Andreas Viestad's cooking show, "New Scandinavian Cooking", and it's a bit different than you may expect of the cuisine... it's definitely more garlicky than I would have thought. And despite all the vodka, it's not boozy at all. In fact, I actually used aquavit in place of the vodka and it added even more interesting flavor. If you use a smaller roast, be sure to adjust the oven time accordingly; sirloin roast can go from perfect to too dry very quickly.
04Remove the meat from the bag and reserve the marinade. Heat the vegetable oil in a large nonstick skillet over high heat and sear the roast on all sides, about 4 to 6 minutes.
05Transfer the meat to a roasting pan and roast in the middle of the oven, turning once, for 1 to 1-1/4 hours or until a meat thermometer registers 130 degrees F; and before the roast is done, pour the reserved marinade over it (you can do it when you turn the roast over, as I did -- ).
06When done, transfer the meat to a cutting board and let it rest, uncovered, for at least 20 minutes; set the roasting pan aside.
07Just before serving, pour the cooking juices into a saucepan and heat gently. Stir in the butter, season with salt and pepper and the remaining 1 teaspoons thyme. Strain the sauce and discard the herbs.
08Carve the roast and arrange on a platter with the sauce on the side.
