Uncle Bill's Sweet and Sour Sauce

In a medium skillet combine the vinegar and sugar and bring to a boil, stirring frequently. Add pineapple juice concentrate, monosodium glutamate, ketchup, soy sauce, seasoning salt and garlic powder and bring to a boil. Stir until well blended. Add red food coloring.
Meanwhile, in a cup mix together water and cornstarch until fully dissolved. While sauce is boiling, add cornstarch mixture slowly, stirring continuously until the mixture thickens slightly. Do not add mixture all at once as the sauce could get too thick. Use only enough cornstarch to thicken to your desired consistency. When desired consistency is reached, voila! The sauce is ready!
