Sweet and Sour Sauce
Not exactly authentic I'm sure, but it fits our needs and we like it.
1 (6ounce) can pineapple juice
1/4 cup white vinegar
2/3 cup sugar
1/3 cup ketchup
2 tablespoons cornstarch
In medium saucepan, over medium heat, mix together all ingredients. Bring to boil and cook until thickened.
