Sweet and Sour Sauce

Pork, chicken, shrimp, meatballs, you name it: this sauce goes with everything!  It is great over rice.  Mixed with sauteed onions, bell peppers, and pineapple, I could eat this every day for a month!  I'm not joking.

Mix all ingredients in a bowl, then heat in a saucepan, stirring, until it thickens.

1/4 cup soy sauce
1/4 cup ketchup
1/2 cup pineapple juice (reserve the pineapple to add later)
1/4 cup white vinegar
1 T brown sugar
1 T white sugar
1 T corn starch
