I might have to try making the blueberry lime jam some time. Do you just eat it on toast? I made plain blueberry a few times, and it was the best jam for peanut butter and jelly sandwiches, but it never sets firm enough for my liking.

I have a recipe for "nectarines, grapes, and blueberries with orange and cardamom" from Cook's Illustrated that I've been meaning to try out. You can get the recipe from their website if you sign up for a 14-day trial membership.

"Cantaloupe, plums, and cherries with mint and vanilla", "Honeydew, mango, and raspberries with lime and ginger", and "Peaches, blackberries, and strawberries with basil and pepper" were other interesting fruit salads in the same article about muddling.
