To prepare a syds turkey gravy sauces recipe, first you'll need to prepare your turkey. First, cut the turkey in half lengthwise. Then, place the cut side down on the bottom of the pan. Place the chopped onions, celery, carrots, and garlic into the saucepan. Cook the onions over medium heat, stirring occasionally, until they're soft and translucent, about 5 minutes. Add the tomato paste and cook until it's thickened, but not mushy, 2 to 3 minutes more. Remove the mixture from the heat and add the remaining ingredients. Allow the sauce to simmer, covered, for 1 to 2 hours, or until the meat is no longer pink in the center.
