Place the hot water, oil and salt in a large pot over high heat; cover and bring to a boil. When water reaches a rolling boil, add small amounts of spaghetti at a time to the pot, breaking up oil patches as you drop spaghetti in. Return to boiling and cook to al dente stage (about 4 minutes if fresh, 7 minutes if dry); do not overcook. During this cooking time, use a wooden or spaghetti spoon to lift spaghetti out of the water by spoonfuls and shake strands back into the boiling water. (It may be an old wives'tale, but this procedure seems to enhance the spaghetti's texture.) Then immediately drain spaghetti into a colander; stop cooking process by running cold water over strands. (If you used dry spaghetti, first rinse with hot water to wash off starch.) After the pasta has cooled thoroughly, about 2 to 3 minutes, pour a liberal amount of vegetable oil in your hands and toss spaghetti. Set aside still in the colander.
Meanwhile, thoroughly combine the seasoning mix ingredients in a small bowl and set aside.
In a 4-quart saucepan, combine 1-1/2 sticks of the butter, the onions and garlic cloves; saute over medium heat 5 minutes, stirring occasionally. Add the minced garlic and the seasoning mix; continue cooking over medium heat until onions are dark brown but not burned, about 8 to 10 minutes, stirring often. Add 2-1/2 cups of the stock, the Worcestershire and Tabasco; bring to a fast simmer and cook about 8 minutes, stirring often. Stir in the tomato sauce and bring mixture to a boil. Then stir in the sugar and I cup of the green onions; gently simmer uncovered about 40 minutes, stirring occasionally.
To finish the dish, for each serving melt 2 tablespoons butter in a large skillet over medium heat. Add
one-sixth of the cooked spaghetti (a bit less than a 2-cup measure); heat spaghetti 1 minute, stirring
constantly. Add 1-1/4 cups chicken and sauce and 2 tablespoons of remaining stock; heat thoroughly,
stirring frequently. Remove from heat. Roll spaghetti on a large fork and lift onto a heated serving plate.
repeat process for remaining servings.
