Shepherd's pie is an English dish of minced lamb simmered with onion, carrots, tomato purée and Worcestershire sauce, topped with buttery mashed potato and baked. The "shepherd" in the name refers to the lamb: the same dish made with beef is called cottage pie. The meat simmers for 40 minutes in stock before going into the oven.
Tender lamb in a rich, reduced sauce, slightly sweet from the carrots and sharpened by the Worcestershire, under a soft mash whose fork ridges turn crisp in the oven.
