Blanch the Blueberries
Blanching the blueberries before canning them helps to preserve as much of their flavor and texture as possible. This step makes it possible to use your canned berries later much as you would the fresh fruit - on yogurt, in pancakes and muffins, etc.
Use tongs to hold onto the knot end of the cheesecloth bundle of blueberries. Dip it into the pot of boiling water and gently swirl the bundle back and forth for 30 seconds.
You may see some juice stains appear on the cheesecloth. This is normal.
You can reuse the cheesecloth for subsequent batches of blueberries, or rinse and dry it for another future use.Continue to 6 of 7 below.

If you have more blueberries that you want to can, proceed with each pint as above.Continue to 7 of 7 below.

Can the Blanched Blueberries
Process the pint jars of blanched blueberries in a boiling water bath for 15 minutes.
If you decide to do quart jars rather than pints, process them for 20 minutes.
The fruit may shrink a little and exude some juice during canning. This is normal.
Unopened jars of canned blueberries will keep at room temperature for 1 year. They are still safe to eat after that, but their quality will decline. Store opened jars of canned blueberries in the refrigerator.
