Freshly ground lamb is the best to use when preparing shepherd's pie. Make sure to use the ¼ dice to achieve the proper texture, and choice cuts of lamb are not necessary. Be sure that the meat and grinder are thoroughly chilled before using. Brown the meat and vegetables separately. You'll finish this dish by mixing the vegetables, meat and seasonings together and topping with potatoes, mashed. A splash of beer will add a kick to this comfort dish.
