Put large stock pot of water on to boil with 2 tablespoons salt. When water boils, add 3 regular pkg. of linguini noodles and boil until done, but still firm. Noodles can be boiling while you are making your sauce. In another large stock pot, melt 1 stick of real salted butter and 1 stick of Blue Bonnet Margarine. Add about 3 teaspoons of granulated garlic, about 1 teaspoons salt, 1 teaspoons Italian seasoning, 1 teaspoons parsley and 1 teaspoons black pepper. Boil for a couple minutes. Add 2 pkgs. Of uncooked, frozen shrimp without tails. Cook about 7 minutes on high temperature Remove shrimp with slotted spoon and set aside on plate. To the remaining liquid butter, add 1 heaping tablespoons of all purpose flour. It will thicken immediately so stir quickly. Keep on burned for a bit, stirring briskly with slotted spoon or whisk until all lumps are gone. Remove from burner to prevent burning and stir. This rue is very thick right now. To the thickened rue, add about 2 more teaspoons salt, 4 chopped, green onions with most of stem, 2 pints of heavy cream, 2 tablespoons parsley flakes, 1 cup of parmesan cheese, and 1 tablespoons of granulated garlic. Stir and cook on high heat for about 7 minutes. Add about 3 cups of milk, another stick of Margarine, and the shrimp. Stir and cook over high heat, stirring very often for about 10 minutes. Add 2 cans of minced crab without the juice and another 1 ½ cups parmesan cheese. Boil and stir for another 7 minutes or so. While it’s boiling, In a small bowl, put 1 heaping tablespoons flour. Using a regular soup dipper, add 1 dipper of boiling sauce to flour. Stir flour mixture with whisk until no big lumps remain. Add one more dipper of boiling sauce to flour mixture and stir again until mixed. This will still have small lumps. Into boiling Sauce, add the flour mixture slowly about 1 tablespoons at a time, while stirring constantly. Let sauce boil while stirring constantly for another 7 minutes or so and remove from heat. Sprinkle each portion with Grated Parmesan cheese. Serve immediately with French Bread slices, grilled in garlic butter! A salad also goes nicely with this meal. This Alfredo Sauce should not be really thick like gravy. It is very flavorful and not that expensive to make. The sauce will thicken a little more as it starts to cool down. Great for left-overs! Kids love this even with the green onions! Don’t tell them the onions are there and they will think the green stuff is parsley!
