Blueberries are still showing up at the farmer's market. If you love blueberries, you should consider putting up some blueberry jam. I did. Now I have little jars of summer sitting in my pantry, ready to open on a bleak winter's day. But you had better hurry....blueberries won't be around much longer.
If you haven't done any canning, you should do a little reading first. This is a good site, loaded with information http://www.pickyourown.org/water_bath_canning_directions.php . Don't let canning frighten you. Generally speaking, be sure you read through your recipe and plan to do your canning on a day when you do not feel rushed and you can give it your full attention. There are no safe shortcuts when it comes to canning. Blueberry jam is a great place to start. It is practically foolproof. The addition of lime to this jam makes it something special.
