In a large saucepan, melt butter over medium-high heat, add poultry seasoning, and cook for 30 seconds. Next, add the flour and whisk regularly, for about 3-4 minutes. Make sure not to burn. Add the beef broth, chicken broth, and pepper while whisking. Bring to a boil. In a small bowl or cup mix the cornstarch with the water. Reduce heat then whisk the cornstarch mixture in the gravy. Let simmer for a couple of minutes, whisking regularly, or until the sauce thickens. Keep warm until your fries are ready. To cook the fries, heat your oil in a deep fryer to 300° F. Add fries to the oil slowly and cook for about 8-10 minutes, stirring occasionally so they don’t stick. Deep fry until fries are nice, golden, and crispy. Remove fries to a paper towel-lined bowl and season with salt.
