How to Make Blueberry Jam
- Combine blueberries, sugar, lemon juice, and pectin in a large, heavy-bottomed saucepan.
- Bring the mixture to a rolling boil over high heat, stirring constantly.
- Once boiling, reduce heat to medium-high and boil for 1 minute, stirring constantly to prevent sticking.
- Remove from heat and skim off any foam that has formed on the surface.
- Ladle the hot jam into sterilized jars, leaving 1/4 inch headspace.
- Wipe the rims of the jars clean, and place lids and rings on top.
- Process in a boiling water bath for 10 minutes (adjust processing time according to your altitude – check a canning guide for specific instructions).
- Remove jars from the canner and allow to cool completely. You should hear a popping sound as the jars seal.
- Check seals after cooling. Store sealed jars in a cool, dark place for up to 1 year.
