How To: Blackberry / Raspberry Jam

by Elise Schwartz | July 22, 2012 11:00 PM

I had to finish this natural pectin series[1] with a classic jam recipe.  This is another Advanced Plan suitable jam, Blackberry Jam!  You can also switch out the blackberries equally with raspberries or blueberries.  Delicioso!

Blackberry Jam (or Raspberry, or Blueberry Jam)
Makes 4 half pint jars

3 lbs (10 cups) organic blackberries, washed and shaken dry
2 1/4 cups xylitol
Juice of 1 organic orange (rind reserved)
4-5 sanitized half pint jars and lids
1 muslin bag[2] or tea ball[3]

1.)  Mash the berries and decide if you want seeded or seedless jam.  If you prefer seedless, run the berries through a mesh strainer or sieve (You can also add some of the strained berry pulp back to the mix if you want a slightly seedy jam).  Combine the berries, xylitol and orange juice in a large non-reactive pot.  Chop the reserved orange find and put in a muslin bag / tea ball.  Place bag in pot, cover, and set on counter for 3-6 hours.

2.)  Place pot over High heat on stove and bring to a boil.  Skim off any foam along the way.  Stir constantly until jam reaches setting point, around 218 – 222 degrees F (use a candy thermometer).  Test the jam using the ice cube test (hold a spoonful of the jam over an ice cube for a minute or so and see how well it gels.  If it doesn’t form a giggly skin, it needs to boil a few minutes longer.  Test again until gel point is reached).

3.)  Remove bag of orange rind and discard.  Ladle jam into jars leaving 1/4 inch room at top for air.  Push out air bubbles with a spatula.  Put lids on and place jars in pot of boiling water for 10 minutes.  Remove jars and set on counter to cool.  Check lids for proper seal after about 15 minutes before dumping out hot pot of water from the stove.
