Go to the bottom of the page (under the 6th recipe) and there are even more ideas of what to do with cranberries.  These are good ideas for me to have because even though no one in our house has diabetes, it's good to know recipes using real cranberries (not canned) because they are generally low in sugar, especially the whole berries (frozen) that most women buy during the Thanksgiving holiday. 

Some of these ideas would make perfect gift ideas for Christmas presents for your diabetic friends - and you can always use sugar substitutes in the actual recipe if it calls for more sugar than you want to use.
