My sis and I pulled this dinner together a while ago for her boyfriends uncle's birthday. The rack of lamb that we bought from the butcher at le Bon Marche was a parfait piece of meat and the butcher gave us super simple cooking instructions. Salt, pepper, mustard the lamb and then sear it quickly on both sides and into the oven for 20 minutes at about 180 celcius. We served this with very buttery, creamy truly french puree de pomme de terre, a bright and fresh nutty homemade pesto and simple green beans. This meal is classic and an easy one for entertaining.
