I stopped at a peach farm with my kids last week in North Carolina and bought a giant basket of lovely peaches. I made 20 jars of yummy peach jam! I also made Blackberry and Strawberry jam......55 jars total. We are set for jam till next summer!
Blackberry Jam Recipe yields 9 cups:
5 cups of crushed berries
7 cups of sugar
1 package of fruit pectin
(I added a 1/4 teaspoon of butter to reduce the foam)
Measure sugar and set aside.
Put the berries in a large cooking pot. Add 1 package of fruit pectin to the berries and bring to a rolling boil. Quickly add the sugar, stirring until mixture boils again. Boil for 1 minute and then quickly ladle jam into already washed hot jars.
Screw on the lids tightly. I don't have a canning pot so I boiled my jars in a pasta pot! Works great. Fill the pot with water, covering jars with at least an inch of water, and boil for 10 minutes. Jam should set up within a day. Enjoy.
