In a large saucepan or stockpot, combine 4 cups water with the milk, bay leaves, and peppercorns. Bring to a simmer and then poach peeled salsify; cook just until the salsify is soft, but not mushy. Remove the salsify from the poaching liquid, and refrigerate. Once the salsify is cooled, wrap 1 slice of bacon around each stalk of salsify.
Preheat the oven to 350 degrees F.
Roast the bacon wrapped salsify in the oven until the bacon browns slightly, about 10 to 15 minutes.
Meanwhile, in a medium ovenproof skillet, melt 1/2 stick butter over medium-high heat. Add elk tenderloin to hot pan and sear until browned on both sides, and then transfer pan to oven and roast until cooked to desired doneness. (Be careful, as elk tenderloin cooks quickly.)
In a medium skillet, melt 1/2 stick butter over medium-high heat. Add Jerusalem artichokes and saute until the edges turn slightly brown. Then add shallots and saute for 1 minute more. Add arugula and remove from heat.
In the center of the plate, make a circle of wild mushroom sauce. Place the salsify on top of the sauce, and the artichoke-arugula mixture on top of the salsify. Slice the elk tenderloin and place on top of the artichoke-arugula mixture. Garnish with chives.
Melt 1 stick butter in a large skillet over high heat. Add mushrooms and saute over high heat until browned. When mushrooms have browned, add 3 ounces diced shallots and the thyme. Cook mixture for 2 minutes more and then add cream. Reduce heat to a simmer and cook until the cream has reduced by half. Next, pour mixture into blender*, add sherry vinegar and foie gras, if using, and blend until smooth. Season with salt and pepper to taste.

When blending hot liquid, first let it cool for five minutes or so, then transfer it to a blender, filling only halfway. Put the lid on, leaving one corner open. Cover the lid with a kitchen towel to catch splatters, and pulse until smooth.
