Valerie with Steamin' Jam |
Example Pot of Jam |
While this is happening, fill a really large pot with water, so the water will cover the jars with at least 2" of headroom, until the water is boiling. Also be sure you have a rack or steamer basket for the bottom of the pot, to lift the jars off the bottom when processing, allowing the boiling water to surround the jars.
Take your new canning jars (you'll need 8 half-pints), lids, and rings, and wash them in hot, soapy water. Then put the jars only in the boiling water for about 5 minutes, remove to your towel covered counter, and dry these off.
Ladle the jam into each jar, leaving about 1/4" at the top, wipe the rim clean, then put on the lid and ring and twist shut. Put the jars in the rack or lower the jars onto the steamer basket in the boiling water. This is where a jar lifter would really come in handy, but if you don't have one, carefully use tongs. Leave the jars in the boiling water for 20 minutes, then even more carefully remove them from the pot and onto the towel covered counter. Gently wipe any remaining water off the jars and leave on the counter overnight.
Within just a few minutes of placing your jars on the counter you will hear this little ping. Then another one, and so on. That's the sound of your jam saying good job. One last thing is the next day use your thumb to push on the lid and when nothing happens - Congratulations, you have just made your very own, homemade, easiest jam ever plum & blackberry jam. Not only is this a great jam for putting over a schmear of goat cheese on an English muffin, but it's very tasty with vanilla ice cream, and I'm sure you will find many other ways to use this tart, tasty, fruit, easy jam. Yes we can!
