Preparing Fresh Blueberries
First, sort through your blueberries and pick out any that are soft or moldy. Rinse the good ones under cold water. Let them drain in a colander for about 10 minutes so they are not too wet.
After washing, crush the berries using a potato masher or fork. This helps release their juice and flavor. You want about 4 cups of crushed blueberries for a standard recipe.

Check the berries for any stems or leaves before moving on. Using fresh, ripe blueberries will give you better jelly with a stronger color and taste.
Sterilizing Jars and Equipment
Use glass canning jars designed for canning. Wash them with hot, soapy water first. Rinse well to remove all soap.
Sterilize jars by boiling them in water for at least 10 minutes. You can also sterilize them by running them through a quick rinse cycle in the dishwasher.

Do the same with lids and bands, but don’t boil the lids. Instead, soak them in hot, but not boiling, water. Use clean tongs to handle the jars and lids to keep everything sterile.

Prepare Jelly Mixture:
Measure 4 cups of the blueberry juice into a large saucepan. Stir in fruit pectin. Bring to a full rolling boil over high heat, stirring constantly.
Add Sugar and Boil:
Add all 5 cups of sugar at once. Stir to dissolve and return to a full rolling boil. Boil hard for exactly 1 minute, stirring constantly.
Test Jelly Consistency:
Remove from heat. Skim off any foam with a spoon.
If desired, test jelly by placing a small amount on a cold plate; if it wrinkles when pushed with a finger, it’s ready.
Add Lemon Juice:
Stir in 1 tablespoon lemon juice.
Fill Jars:
Using a ladle and funnel, fill hot sterilized jars with jelly, leaving 1/4 inch headspace. You can easily measure the headspace with this inexpensive canning funnel. Wipe rims clean, place lids on jars, and screw on bands fingertip-tight.
Process in Boiling Water Bath:
Place jars in boiling water canner, making sure they are covered by at least 1-2 inches of water. Process for 10 minutes (adjust time for altitude if necessary).
Remove jars and let cool undisturbed for 12-24 hours.
Check Seals and Store:
After cooling, check seals by pressing center of lids; they should not flex up and down.
