– I do love homemade jams. My mother taught us to can. I helped her every summer. When my husband came home with a box of plums, visions of plum jam danced in my head. Usually he brings home peaches from the Central Valley, but, alas, they did not have any peaches this time. It’s always exciting to try something new.
Out came the canning equipment and books. I always refer to the book, Ball Blue Book Guild To Home Canning, Freezing & Dehydration, for any question I have. Great book for beginners.
The jars and equipment are hand washed before using. I NEVER place the jars into the dishwasher. After awhile dishwasher detergent pits the glass and makes it look foggy. I prefer the jars to look crystal clear!
After they are cleaned, place the jars into a large pot filled with water as you put the jars in. This way you don’t over fill the pot with water. Bring the water to a boil and boil jars for 10 minutes. Turn the heat off and leave jars in boiling water until time to use. I pour boiling water over the lids, rings and utensils and leave in water until time to use. I want everything to be sterile.
I used my new book, Better Homes and Gardens Can It!, to see how to cook plums. Chop up and pit the plums and measure 8 cups of the cut plums and put into a sauce pan with 1/2 cup of water. When the mixture begins to boil, cover the pan and simmer for 5 minutes. Remove from the heat and pour the mixture back in to the measuring cup to make sure you have 6 cups of plums. Pour mixture back in to the sauce pan and add 7 cups sugar and 1/2 cup of lemon juice. Stirring constantly until rolling boil. Add liquid pectin quickly and bring to rolling boil, stirring constantly for one minute. Remove from heat.
Fill jars to 1/4 inch from the top. Take a paper towel dip into hot water, and wipe jar rims. Place seal and ring on the jars.
Screw the lids on until you feel resistance. They should be snug.
Place jars into the large canning pot with water and cover.
You can hear the jars seal. After all the jars are sealed, remove the rings. This keep the rings from sticking to the jars and making it almost impossible to open. If you give any as a gift, you can replace the ring after cleaning the jar and ring.
Enjoy! 🙂 Look for my plum butter.
