Place a large dutch oven over moderate heat. Once hot, add the bacon and cook until crispy. Use a slotted spoon to remove the bacon onto a paper towel lined plate. Set aside. Remove all but 1 tablespoon bacon grease.
Add the butter. Once melted, stir in the onion, celery, and garlic. Season with the oregano, thyme, paprika, bay leaves and a small pinch of salt and pepper. Stir in the flour and cook for 30 seconds or so. Then slowly stir in the chicken stock, half and half, clam juice (both bottled and the juice reserved from the canned clams as well), half and half and Worcestershire sauce.
Cook over low heat, stirring occasionally, until thickened. Stir in the tortellini and clams. Cook until the tortellini have softened slightly, about 5 to 8 minutes. Give it a taste and adjust seasoning accordingly. Remove bay leaves and serve. Top with the crispy bacon from earlier, oyster crackers, parsley, hot sauce and lots of coarse black pepper. Enjoy!
