I don't have any specific recipes, but there are lots of recipes that use other fruits; I'm thinking of a cherry and port wine one I saw somewhere. I'll do some nosing around and see what I can find.
Ooh - just remembered, too, saw a 'Blueberry BBQ sauce' recipe somewhere, also - that would be neat!
Blueberry bbq sauce - ohhhhhhhhhh yum!!! I'm forever on the hunt for new blueberry recipes, and since I've made pork dishes with all sorts of fruits (pears, apples, pineapple, peaches, etc) I got the idea perhaps someone out there had tried pork with blueberries.
