Crush the saltines in a bowl and add all the dry ingredients, butter, herbs, celery and onion. Slowly add enough stock or boullion water to make the crackers wet and sticky (the whole 2 cups may not be necessary). Mix the stuffing and add more poultry seasoning and pepper to taste (I mix with my hands and enjoy a dash of Creole seasoning such as Slap Ya Mama from time to time for a kick). Stuffing may be refrigerated for a day or two in advance. Cook in a greased casserole dish until warmed through and crisp on top, or stuff inside a turkey or chicken and cook until bird is done and internal temp reaches 165*F. Top with butter or baste with pan juices as desired throughout the cooking process for a crispy, flavorful crust.
