Melt bacon fat. Add the flour, and stir constantly over medium heat until dark brown, taking care not to burn. This takes 30 minutes. If mixture smells liked burned bacon, throw away and begin again. Lower heat and add okra, green pepper, celery, onions, and garlic. Sauté until onions are soft. Add stock, tomato paste, seasonings, and bouillon cubes. Simmer for 2 hours. Add chicken, turkey, and or shrimp 15 minutes before serving. Add Tabasco to taste. Freezes well. Yields 5-6 quarts.
