Blackberry Jam

Gather together the equipment listed on the Making Homemade Jam page and wash all jars. The method shown here is using store bought pectin and regular sugar. I have found that cane juice crystals tends to leave the jam watery. So when I want to make jam using a different type of sweetener I use the Pomona Pectin.

You will need a box of pectin for each batch of jam made. I use Sure Jel but there are other brands of pectin that will work equally well. You can find it in the grocery store or Walmart where the canning supplies are found.  Inside the box of pectin will be the recipes you need for making jam.


Gather you canning jars together and wash them.  You will want to keep them hot while you are making jam.  You can leave them in a hot dishwasher, put them in boiling water or what I do is to put them in my sink and fill them with boiling water and let them sit until I need them.

Next get your canning rings and new lids put into a pan of water.  Let this get very hot, but don't boil them

Now it is time to prepare your fruit.  Start with fresh fruit and measure out several cups into another bowl and begin by mashing the berries with a potato masher.

Measure out your sugar ahead of time

Measure out the amount of berries called for in the recipe.  For this batch of jam I needed 5 cups of mashed berries.   Put these in a large 4 or 6qt pot.  Open the package of pectin and sprinkle it in and stir until it is dissolved.

Put this on the stove, on high, and bring to a full rolling boil.  This is a boil that can not be stirred down.

When you have a strong full boil going add the sugar

Stir and mix well and bring mixture back to a full rolling boil once again.  Once it has reached the strong boil, stir and boil for one minute. Remove from heat and begin filling your jars.  Take a hot jar and set the canning funnel on the top of the jar. I use a clean measuring cup to fill jars.

 

Once the jars have been filled it is time to use the lid wand to put lids on the jars. First wipe the jars edges and tops with clean wash cloth.  If there is jam on the rim of the jar the lid will not be able to seal.  Then put a lid on followed by a ring.  Tighten the ring until it is "just tight".

Now put the jars into your canner of boiling water

Cover the canner and bring to a boil.  Let the jars boil for a time that is according to the size of the jar.  Half-pints you boil for 5 minutes, pints for 10 minutes. 

Remove the jars and set them on the counter undisturbed for 24 hours.

After 24 hours check to make sure each jar has sealed.  You may remove the rings and they are ready to stored in  your pantry!
