Well, my sister has been at it again.  This time she made homemade Blackberry Jam!  She is totally making me look bad.  My husband looked up from his cellophane wrapped to-go box and said, “Why don’t you like to cook like your sister?” Hey, I’ve been telling him to fire me for a long time and he keeps me on anyway.  Ha!

It’s an attention span thing.  And besides that, it gives me an excuse to visit my sister and come home with all kinds of home-cooked goodness!   This recipe looks easy enough for even me to be able to do it.  Imagine that!  So, here is another episode of “Lynda’s Kitchen” for those of you that enjoy that cooking thing…

For this recipe, Lynda used:

5 cups crushed blackberries
7 cups sugar
1 package regular powdered fruit pectin

Prepare your canner, jars, bands and lids.  Make sure you boil your jars and bands for 10 minutes and then turn down to simmer to keep them warm.  Do not boil the lids, only simmer. Tip:  Hot food into hot jars and cold food into cold jars.

Prepare the berries by washing gently and removing any stems or dirt and any moldy or dried up berries.  Pretty, aren’t they!

Crush with a potato masher but don’t crush them to oblivion,  this is a jam you want to have some intact pieces so it’s yummy. Crush berries until you have five cups crushed.

Place the berries into a deep stainless steel saucepan and whisk the powdered pectin into the crushed fruit until it is dissolved.  Bring to a boil stirring frequently.  This step is essential to dissolve the pectin.  Add the sugar and return the mixture to a full rolling boil that won’t stir down.

Boil for one minute and then remove from the heat and skim off the foam.  I use a large tablespoon to do this and if you just barely skim the top of the foam with the back of the spoon the foam will stick to the spoon.

Don’t skip this step because you really don’t want foam on your jelly.

Ladle hot jam into hot jars and leave 1/4″ head space.  Wipe the rim and place a lid and band on the jar tightening only until resistance is met and then increase until fingertip tight.  Place the jars in the canner with about 2″ of water covering the jars. Bring to a boil and process for 10 minutes.

Remove jars and let them sit undisturbed for 24 hours.  This recipe makes about 7 half pint jars.

You will hear the beautiful sound of “ping” when the jars have sealed.  I love to hear this sound and frequently make a spectacle of myself when I hear it.  My family just rolls theirs eyes now when I get all excited about the jars sealing.

Lynda, thanks so much for showing us how it is done.  And if you have any leftover berries, remember that Blackberry Cobbler is always a hit.
