Aunt Ruth's Cranberry Sauce

My dear Aunt Ruth passed away 2 years ago, at the age of 96. She used to make this 'special' recipe for family Holiday dinners. She wrote it down for us in 1972. If the turkey doesn't put you to sleep, this will help.

1 package fresh cranberries
1 cup port wine
1-1/2 cup sugar

Boil this mixture until the berries pop. Add about 5 level teaspoons corn starch to an additional 1/4 cup port wine. Add this to hot mixture and simmer until thickened, stirring occasionally. Chill before serving.
