Here's a fabulous recipe I found somewhere online:
bag o' cranberries (I used a mix of frozen and fresh)
3 cups raspberries (trader joe's frozen for me)
1/2 cup sugar
1/3 cup crystallized ginger.
Chop the ginger by hand (the food processor didn't manage it well for me.) then toss it and cranberries into food processor. Grind it up, but not to a pulp. Just enough. Add sugar and then sprinkle in the frozen raspberries (not need to thaw them), stir not too hard so most of the raspberries stay whole.
Let it all sit for a few hours. Eat. Oh, boy. YUM.
