Shrimp Gumbo Stock: Add all ingredients to large stock pot and boil over low/medium heat for 1 hr... Strain contents, put liquid stock back in pot... Discard the rest... Now you have shrimp stock for your gumbo... Gumbo: Make roux, or use store bought roux... Add 1/2 cup or so roux to pot, stir roux very well in stock on high heat... As you stir make sure roux does not stick to bottom of pot... Then add onion, bell pepper, and celery, to stock and stir often, boil over low/medium heat for 1hr... Add shrimp to the pot, and cook for 20 minutes... Season to taste... Server over cooked long grain rice, with potato salad, and garlic bread... Gumbo is better the next day...
