After picking all these wonderful berries lately I just had to can something! Here's my recipe for canning your own jam PLUS it's super easy!
Blackberry / Blueberry Jam
2 cups each Berry
1.5 cups sugar
1 green apple, grated
1/2 cup fresh lemon juice
Bring to boil for twenty minutes until beginning to stick to bottom (removing foam from top). Test a bit and if it doesn't run your great! Funnel into pre-sterilized jam jars put on lid and ring then flip over and let cool completely. If lid don't "pop" it is correctly sealed and will keep one year, if not, refrigerate and use in 3 weeks.
So make your own Berry jam and share with family and friends AND remember to use local, organic ingredients. Enjoy!
