DEMIGLACE RECIPES

Steps:

• Preheat the oven to 450 degrees F.
• Pour the oil into a metal roasting pan and put it in the preheated oven for 3 to 5 minutes to heat up the pan and condition it with the oil. Spread the bones out on the roasting pan and cook until browned, 30 to 45 minutes, turning the bones occasionally so they brown evenly.
• Transfer the bones to a large-enough stockpot to accommodate the bones, 6 quarts ice water and more. Use tongs to transfer the bones so you do not pour any fat into the stockpot. Add the ice water to the stockpot and bring to a simmer. Allow the stock to cook for 4 hours at a slow simmer. Skim the surface of the stock occasionally to remove any fat or impurities.
• While the stock is simmering, discard all but about 1/4 cup of the fat from the roasting pan. Bring the pan back up to temperature over high heat on the stovetop. Add the onions and carrots and cook until golden brown and caramelized. Add the celery and cook for another 10 minutes. Stir in the tomato paste, thyme and bay leaf and cook, stirring regularly, until the tomato paste gets a brick red color, about 15 minutes. Add 1 cup of the red wine and stir it into the mirepoix (vegetable) mixture.
• Add the mirepoix mixture to the stock after the 4-hour simmering time. Bring the stock back up to a simmer and continue to cook it for another 2 hours.
• In a separate pot, bring the remaining 7 cups red wine to a boil and cook until reduced by half, 15 to 20 minutes.
• When the stock has simmered for 6 hours, strain it through a chinois and combine the strained stock with the reduced red wine. Bring the stock to a boil, lower the heat to a hard simmer and reduce the stock until it has a consistency that coats the back of spoon and is about 2 quarts (8 cups) in volume, up to 1 hour. Season with salt and pepper and then strain the sauce though a chinois again.

Steps:

• "First, make the reduction. Melt 1 tablespoon of the butter in a large saucepan over medium-low heat. Add the diced shallot and cook untile softened, about five minutes. Then, add all of the port (yes, a whole bottle!), and the thyme sprigs, and bring to a boil over high heat. Watch for the boil, then reduce the heat to maintain a brisk simmer. Cook until the port has reduced to the consistency of corn syrup, about 30 minutes. You should have about 1/2 cup or so including the diced shallot. At the same time, bring the chicken broth to a simmer in a small saucepan. Once it's brought a simmer, turn off the heat, and add the package of porcini mushrooms. Here, you're creating a mushroom-enriched stock that will add a nice earthy base to the sauce. Let the mushrooms soak for 15-20 minutes. with a straining or slotted spoon, lift the porcini to a small bowl. Strain the sooaking liquid through a coffee filter, paper towel or cheesecloth to remove any dirt sediment that came from the porcini mushrooms. Save the stock -- that's what you're going to use in the next step. Add the enriched chicken stock and half of the porcini mushrooms (diced) to the port reduction. (You can use the other half of the porcini mushrooms in a beef or mushroom-cap stuffing.) Bring the sauce to a boil over high heat, then reduce to maintain a brisk simmer. Cook until it's reduced to about 1 1/3 cups, which is about 15 minutes. Strain again through a fine strainer, pressing on the solid mushrooms and shallots. Add salt and pepper to taste. You should have a little over 1 cup of the sauce. The sauce can be refrigerated at this point and held for up to 2 days, if you seal it carefully with plastic wrap. Twenty minutes before plating your dinner, bring the sauce back to a low simmer, stir. In a separate bowl, mix the flour and butter into a paste, then WHISK rapidly into the simmering sauce to thicken it. You'll need to whisk for 2 minutes or so to give the sauce a single consistency. Raise the temperature to a simmer, and maintain that while whisking for 2-3 minutes to remove any flour flavor. Add a teaspoon or so of fine balsamic vinegar, and taste a few times. You're done! Serving options: Can be plated first, with filet mignon beef medalions on top, or poured over steak. "
