*I used a container of organic cranberries that came in a 7.5 oz box. If you can't find this size, grab a bag of fresh cranberries (these are usually 12 oz). Take a little more than half of the bag. The sauce will still be great even if you have a little more or a little less cranberries. And, if you can't find fresh, frozen whole cranberries will work as well.
**I used Oregon Fruit Products Brand for the tart cherries packed in water. If you can't find these, I can usually find tart cherries packed in syrup from other brands. Drain the syrup off of the cherries (this makes a great sorbet if you freeze it), and use the drained cherries. Instead of the cherry canning liquid, use water in its place. If you can't find canned cherries at all, frozen will also work.
