I have a bag of frozen cranberries I bought on impulse and now I'm not really sure what to do with them. I was thinking of throwing them in a slow cooker with a roaster breast, and maybe some onion soup mix. Any ideas on how this would work? Also, I'm guessing I would have to add liquid. I have a 3-pound breast and a 4-5 quart slow cooker. Any idea how much water to add ? Thanks!
