Answer:
I would try a mixture of not-soft fruits and treat them as though they were cranberries - with a short sugar boil. Apples, oranges, or blueberries would be a selection.
You may want to add a dash of cinnamon, & nutmeg.
Good luck!
12/27/2010-------- I experimented and made a mix that was fab! I don't do percise measurements when cooking, so you'll have to experiment with quantities. Chop about 3/4 to 1 cup of dried sour cherries and peel and chop an apple into small cubes (use a gala or some sweeter apple that has a more firm texture).
Place on medium flame in a small sauce pan with maybe a 1/4 cup of water (maybe a little less or more, you'll have to judge) and 2 tsps or sugar. When sugar has melted and fruit mixture has started to boil, taste to see if the sugar level is good for you. Mixture will taste sweeter when hot so if you think it is too sweet, it will mellow when cooled. When fruit is soft and most of the liquid has evaporated, turn off the flame. Place in a bowl and put in refrigerator to cool.
From there you can possibly add orange rind to the mixture to vary the taste. Would love to know what people think! This is a very good sub for people who can't have cranberries because they are on the anticoagulant coumadin.
