Classic Shepherd's Pie
This is classic Shepherd's Pie, or Cottage Pie, if you want to be technical about using beef instead of lamb. What makes this version work is the potato topping; enriching the mash with egg yolks allows it to bake into a firm, golden-brown crust, giving you those crispy ridges that contrast with the rich gravy underneath.
