1 (15 ounce) can whole kernel corn, drained
1/2 cup white sugar
1/4 teaspoon salt
1/4 cup cold water
1/4 cup blueberries
1/4 cup white vinegar
1/4 cup water
1/4 cup butter, melted
In a medium bowl, combine cornstarch, salt and water. Bring to a boil, stirring occasionally. Reduce heat, cover and simmer, stirring occasionally until cornstarch has set, 60 to 90 seconds.
If desired, slightly thicken the mixture with the sugar/salt and vinegar. Add the peanut butter or margarine, if desired, and season with salt and 1/4 cup hot water. Simmer in a covered dish 1 hour, or until thickened, and sauce is thick enough to coat the back of a spoon.
