Marinated Roasted Lamb

Combine the lemon juice, red wine, red wine vinegar, Dijon mustard and brandy in a microwave-safe mixing bowl. Whisk in the olive oil a little at a time. Add the rosemary, garlic, thyme, oregano, salt and pepper.
Trim the fat from between the ribs and trim the excess covering of fat from the meat.
Place the lamb in a container or large plastic roasting bag, pour the marinade over the lamb, and refrigerate overnight. Remove the lamb from the marinade (reserve marinade) and let lamb sit for 30 minutes at room temperature before roasting.
In a small saucepan bring the reserved marinade to a boil, reduce heat and simmer for 5 minutes.
In a heavy saute pan over high heat, sear the lamb for 1 to 2 minutes on both sides.
Place the lamb on a rack in a roasting pan and then place in the oven, reduce the temperature to 400°F, and roast for 20 minutes or until done. Remove the lamb from the oven and let sit for 10 minutes before slicing.
Serve with the cooked marinade, as desired.
