How to Make Homemade Blueberry Jam

It’s so easy and fun to make your own jam. Blueberry jam is one of my favorites!
This recipe makes 5 ½ x half pint jars – 5 to store or give as gifts and ½ for you to eat right away.


4 cups blueberries, crushed* (about 6 cups whole berries)
3 tbsp lemon juice
4 ½ tbsp classic pectin
3 cups sugar

* to crush blueberries, place in a single layer in the bottom of your pan and crush with a potato masher.


8 qt. pan for jam
Smaller pan for extra hot water
Large pan/stockpot for canning – I use a 21 qt. canner that has a jar rack as well.
6 half pint mason jars
Jar-lifting tongs
Magnetic lid lifter or tongs

– wash jars and lids with hot and soapy water and rinse well.
– to sterilize jars, place jars in canner with just simmering water. Leave the jars in there until ready to use.
– warm lids (do not boil) in smaller pan.
– in 8 qt. pan, mix blueberries and lemon juice. Gradually stir in pectin.
– bring mixture to a boil on high heat, stirring constantly.
– add sugar all at once and stir to dissolve. Bring to a hard boil (that can’t be stirred down) and then boil for 1 minute.
– remove from heat and ladle into hot jars. Fill to about ¼ inch from the top.
– make sure there’s no jam on the rim of the jars that could affect the seal. Clean with a damp cloth.
– place lids on top of jars and screw on bands until finger tight.
– place jars in canner and lower into water. Make sure there’s at least 2 inches of water over the top of the jars. Bring water to a boil and process jars for 10 min. Use the following chart to adjust water canning times for different altitudes:

Altitude (feet)           Increase processing time

1001 – 3000                       5 minutes
3001 – 6000                      10 minutes
6001 – 8000                      15 minutes
8001 – 10000                     20 minutes

– turn off heat, remove lid and allow jars to sit for 5 min.
– remove jars from water and place on a towel for at least 12 hrs. During this time you’ll hear each of the lids pop as they seal.
– check the jars have sealed properly – they shouldn’t move up and down when you press in the middle of the lid. If a jar hasn’t sealed, you can refrigerate it and eat it or you can process the jar again using a new lid.
– keep processed jars in a cool, dry and dark place. They will last for about 1 year.
