For the gravy:

For the potatoes, pre-heat the oven to 400°F. Roast the potatoes on a baking sheet for 1 hour and 15-20 minutes; let cool. Remove the potatoes from their skins and pass them through a ricer.
Bring a medium size saucepot of water to a boil. Salt the water and cook the celery root until very tender, 20 minutes. Drain and pass through a ricer; add to the potatoes. Combine with the butter and egg yolks; season with celery salt, pepper and nutmeg. Fit a pastry bag with a 3/4-inch star tip. Line a baking sheet with parchment paper, then pipe out 12 cones 2 1/2-inches wide and a couple inches high. Beat the egg with cream and lightly brush the cones.
For the meatloaf, melt 2 tablespoons butter over medium heat in a small skillet. Add the breadcrumbs, then season with celery salt and pepper and toast to golden. Remove from the heat and cool. Toss the toasted breadcrumbs with parsley and moisten them with apple cider. Set aside.
Melt 4 tablespoons butter over medium heat. Add the mushrooms and fennel seed; cook to brown lightly, then season with salt and pepper. Add the shallots, celery, apple, thyme and sage and cook to soften, 6-8 minutes more. Deglaze the pan with Calvados, brandy or sherry and remove from the heat to cool.
Season the meat with salt and pepper, then add the cooled mushroom mix, cooled breadcrumbs, cheeses and egg yolks and mix to combine. Form a loaf on a parchment-lined baking sheet and bake on a center rack at 375°F for 1 hour. Add the Duchess potatoes after 15 minutes and bake for 45 minutes, to crisp.
For the gravy, melt the butter over medium heat in saucepot; add the pepper and whisk in the flour. Bring to a bubble, then add the stock and simmer to thicken. Add the Worcestershire sauce, to taste.
