rack of lamb with red wine sauce

I like to get the 'frenched' racks of lamb that are easily available at Costco or Trader Joes - they are usually about 24 oz. and perfect to feed two of us.  Here I browned the lamb, then roasted it to medium-rare and let it sit about 10 minutes before carving.  The drippings are used to make a red wine-shallot pan sauce.  These are served over some garlic mashed potatoes.
