Sweet & Sour Sauce for Meats

1 cup sugar
1 Tbs. cornstarch, dissolved in 2 Tbs. water
1 cup white vinegar
1/4 cup ketchup

In a sauce pan, add all ingredients. Bring to a boil while stirring. When the liquid has thickened, turn heat down to medium. (If you like a heavier sauce, add more dissolved cornstarch.)
Note: Leftover liquid from fried pork cubes may be added. Also, 1 cup of canned pineapple chunks, drained may be added.
