Most mixed berry jam is blueberries, raspberries, strawberries, and blackberries. I subbed the blackberries with cherries. It's so good.

Ingredients:
*5 cups crushed fresh raspberries, blueberries, cherries, and strawberries (1 1/4 cups of each) (5 cups is after they are crushed)
*1 (1.75 ounce) box of Sure Jell
*1/2 teaspoon butter (optional)
*1 teaspoon lemon juice
*5-7 cups granulated sugar (depending on how thick you want the jam)
Directions:
~Bring your canning water to a boil filled 3/4 full (or more).
~In large stock pot, mash the strawberries (or use a blender or food processor).
~Sterilize canning jars.

~In a large stock pot, mash the strawberries, raspberries, blueberries, and cherries (or use a blender or food processor).
~Add 5 1/2 cups of crushed fruit into stock pot.
~Add 1 package of Sure Jell and 1/4 cup granulated sugar and stir until sure jell is dissolved.
~Add 1/2 teaspoon butter if desired to help prevent foaming (I just remove the foam before putting jam in canning jars).
~Cook mixture of high heat and mixture comes to a full rolling boil (still boils as you stir it).
~Remove from heat and stir in remaining 4 3/4 or 6 3/4 cup granulated sugar.
~Return to high heat to a full rolling boil.
~Once you have a full rolling boil, cook for 1 minute, stirring continuously.
~Remove from heat and skim off any foam (it's ok if you don't get it all).
~Ladle jam into prepared jars, filling to within 1/4 inch of tops.
~Wipe rims with a clean damp cloth to remove any jam.
~Put on lids and rings (finger tight).
~Place jars into canner and cook for 10 minutes.
~Remove jars from canner and set on a towel.
~Allow to cool for 24 hours before moving them.
~Lids should be flat (no bubble) before storing (if a jar Doen't seal, place it the refrigerator or take the lid off, clean the top again and place lid back on. Do another 10 minutes water bath).
