Sterilize the jars: Either put them in hot wash dishwasher cycle so that they are clean and hot by the time you use them, or dunk them in boiling water and keep them hot.
Sterilize the lids: boil the tops in a small pan filled with enough water to cover the lids, keep them hot till needed.
Prepare for canning: bring to boil a large pot of water. There should be enough water to completely submerge the jars and have about an inch of water on top of them.
Make the jam: in a large pot (I like to use my Dutch Oven) with a potato masher slightly mash the fruit, so some juices are released, but there are still some chunks of fruit left. Place the pot on heat, to bring the fruit to boil.
While apricots are warming up, whisk lemon juice and pectin together until pectin is dissolved. Add the juice mixture to the apricots, mix to incorporate. When the juices start bubbling, mix in the sugar and steer with a wooden spoon until completely dissolved. Add the cinnamon, cardamom, and cloves.
Bring the jam to complete boil (when it doesn’t stop boiling if you mix it with a spoon). Lower the heat and simmer for about 10 minutes, taking off the foam if it forms. Note: to lower the foam you can add a tiny bit of butter to the pot.
Jar the jam: carefully remove the hot jar and fill it with the jam using a canning funnel, leaving at least a ¼ inch space between the jam and the edge of the jar. With a clean wet towel remove any excess jam from the edge of the jar. Using a magnetic lid lifter remove the lid, and place it on top of the jar. Secure the lid. Repeat with the remaining jam.
Using the jar lifter, carefully place the jars in the large pot of boiling water, make sure they are completely submerged. Boil for about 10 minutes.
Remove the hot jars using the jar lifter, and place them on a towel. Let cool completely before labeling. Make sure the lid tops are not popping in the center. If they are, they should be removed and re-sealed (same process – wash and sterilize the jar and a lid, bring the jam to boil, and re-can it. It’s very important that the edge of the jar is clean.
It will take a couple of weeks for the jam to set. Store it in a dark chilled place, and patiently wait for the winter!
