1Heat beef tallow in a saucier, add ground lamb, season with salt, and brown while breaking it into a fine mince.
2Add chopped vegetables (carrots, celery, onion, garlic) and use their moisture to scrape up brown bits.
3Add butter, then stir in flour to create a roux; incorporate tomato paste and toast.
4Deglaze with Guinness, add chicken stock, scrape the pan, then add Worcestershire sauce, fresh thyme, and bay leaf. Bring to a boil, then simmer until thickened.
5Rinse potatoes, prick with a fork, season with salt, and bake at 425°F for about 55 minutes or until internal temperature reaches 200°F.
6Season the lamb filling with salt and a splash of red wine vinegar; stir in peas and carrots.
7Cut the top off the cooked potatoes, scoop out the flesh into a bowl, mix with grated cheddar, egg, softened butter, and salt; mash until smooth.
8Fill potato skins with the lamb stew mixture (about 3/4 full), spread a thin layer of mashed potato over the top, then pipe the remaining mashed potato over in decorative peaks.
9Sprinkle with flaky sea salt and bake at 425°F for about 20 minutes until golden and crispy.
10Garnish with chopped chives.
