Black And Blue Jam

Directions

1. 1
   Jars: Sterilize 8 half-pint jars according to package directions. Sterilize all tools that will come in contact with your jam. That's very important when canning.
2. 2
   Crush most of the berries and place them in a large, heavy duty pot. Add the lemon juice and the box of pectin, stirring constantly over medium-high heat. Bring mixture to a boil and add in the sugar, continuing to stir. Bring back up to a boil and continue to stir for 2 minutes. Remove from heat and stir in the butter. Skim the foam off the top if there is any.
3. 3
   Ladle the jam into the hot jars and place the tops and lids on. Process in hot water according to canning directions. There are roughly 8 servings per jar. Keep them all or give them as gifts. I haven't bought a jar of jam since I started making my own. There is nothing better than homemade. Enjoy!
