I think at one time I had a more complicated version of this that I got from one of the Food Network shows, but this is so much easier and just as tasty. Plus the Grand Marnier is not absolutely necessary, except for me.
Grand Marnier Cranberry Relish
1 bag fresh or frozen cranberries
1/2 cup sugar, more if you like
1 orange with zest
2-3 tablespoons Grand Marnier, more if you like, or none at all
Pulse cranberries in processor about 6-10 times. Keep them chunky. Dump in a medium mixing bowl. Stir in sugar. Zest the orange and add to bowl with the juice from the orange. Add Grand Marnier. Mix well and refrigerate several hours. I make mine several days ahead.
This is wonderful on your turkey sandwiches also.
