GREAT NECK KOSHER RESTAURANTS RECIPES

Steps:

• Heat the vegetable oil in a large pot or Dutch oven over medium-high heat. Add the turkey wings and cook, undisturbed, until browned, about 5 minutes. Stir, then continue cooking, stirring occasionally, until browned all over, about 5 more minutes. Add the celery, onion and carrot and cook, stirring occasionally, until lightly browned and tender, about 5 minutes. Add 1 cup water, the thyme and bay leaves; bring to a simmer and cook, stirring and scraping up any browned bits, until reduced by half, about 3 minutes.
• Add the turkey stock and bring to a boil, then reduce the heat to maintain a simmer. Add the dried mushrooms, if using, and simmer until reduced by one-third, about 30 minutes. 
• Mix the butter and flour in a small bowl to make a paste. Stir into the simmering gravy and cook, stirring occasionally, until thickened slightly, 15 to 20 minutes. Season with salt and pepper. Strain through a fine-mesh sieve into a large container. Let cool, then cover and refrigerate up to 5 days. Reheat over low heat.
• Combine the turkey wings, carrots, celery, onion and garlic in a large pot. Add 2 gallons cold water. Bring to a boil, then reduce the heat to low or medium low to maintain a gentle simmer.
• Simmer the stock about 4 hours, occasionally skimming any scum that rises to the surface with a spoon. Strain into another pot, discarding the bones and vegetables. Let the stock cool completely. (For faster cooling, set the pot of stock in a large bowl; add enough ice water to the bowl to come about halfway up the sides of the pot and let cool, stirring the stock occasionally.) Transfer the stock to an airtight container and refrigerate up to 5 days.
