blueberry lime jam

We made yet another variety of jam recently: blueberry lime. It had a really surprising flavor - something you wouldn't get from Welch's in the store, but it is delicious. Our amount of blueberries gave us about 6 half pints of jam. All fruit jams have an inordinate amount of sugar in them. (This one didn't have that whole container, just 5 cups. Which is a lot anyway.) This is the first recipe we canned using my grandma's jars.
