In a large pot over medium heat, melt butter; stir in flour and cook until bubbly. Stir in green onions, chopped onion, bell pepper, celery, garlic, bay leaf, thyme, and basil. Reduce heat to low and cook, uncovered, stirring often for approximately 20 to 30 minutes or until vegetables are soft.
Increase heat to high and add tomato sauce, wine, clam juice, water, Worcestershire sauce, white pepper, and Tabasco; stirring, bring to a boil.
Reduce heat to low and simmer, stirring occasionally, about 45 minutes or until thickened and reduced to 4 1/2 cups. Stir in lemon zest, lemon juice, parsley, and shrimp. Simmer approximately 2 to 3 minutes or until shrimp are cooked.
NOTE: Shrimp should always be cooked quickly in order to preserve their sweet, delicate flavors. They are very quick to cook, and the flavor can easily be ruined by overcooking. Most shrimp cook in as little as 3 minutes - when they curl and turn pink, they are done. Properly cooked shrimp are firm with a gentle curve shape (like the letter "C").
Remove from heat and serve over hot cooked rice.
Serves many.
