Canning is an exact science and I recommend that before you try non-acidic things or spend a great deal of money on a pressure canner, you get used to the basic principles by canning down easier things, like this peach jam!
I use my processor to chop down the peaches into chunks and I recommend you do this!
- 4 1/2 cups chopped fresh, ripe peaches (no skin!)
- 3 tbsp lemon juice
- 3 cups sugar (remove 1/4 cup and set aside)
- 1 package SURE JELL for sugar-free or low-sugar canning
- Combine the lemon juice, the 1/4 cup sugar, and the Sure Jell in a heavy pot, stirring on medium heat until the sugar and gel meltdown
- Add in the peaches and bring to a rolling boil.
- Stir in the remaining sugar and bring it back up to a rolling boil.
- Cook for an extra minute, skimming off foam as you go.
- Ladle into pre-sterilized jars to 1/4" from the top
- Fingertip seal and place back into the canner
- Fill the canner to 1-2" above the jars
- Bring to a boil and boil for 10 minutes.
- Turn off the heat and remove jars from the water- BE CAREFUL NOT TO TILT!
- Set aside to cool and listen for the POP!
- Any that don't pop, just refrigerate and use immediately.
- Let ALL jars cool though and the ones that pop remain on the counter, or other space, untouched for 12 hours or more.
I like to add flavors into mine like a pinch of cinnamon or even some bourbon!
