Peel and remove the tails from the shrimp. Place the skins and tails in a pot and cover with water. Bring to a boil for about 5 minutes. Cut the shrimp into bite-sized pieces and set aside.
Meanwhile, melt the butter in a cast iron skillet over medium heat. Stir in the celery and onion and cook until tender, stirring frequently.
Stir in the garlic, shrimp and scallops. Stir in 1 ½ cups of the boiled shrimp water. Season with Red River Ranch Original. Bring to a good simmer and cook for about 5 minutes, stirring frequently.
Remove the skillet from the heat and stir in the Ritz crackers. Top with the Cheez It crackers.
Bake in a preheated oven at 350 degrees F. for 20 to 25 minutes or until the crust has lightly browned and the bake has set up slightly. Allow to cool 5 minutes before serving.
