A naturally and lightly sweetened refined sugar-free peach preserve consisting of fresh peaches, maple syrup, lemon juice, and vanilla - made simple in an Instant Pot or pressure cooker.
Slice the peaches in half to remove the stones. Discard the stone, and chop up the fruit.
In the Instant Pot insert, stir together the peaches, maple syrup, and lemon juice.
Make sure the gasket is seated properly, then lock the lid in place and ensure the sealing knob is turned to "sealing".
Set for 2 minutes on Pressure Cook (manual/high pressure), then allow the pressure to release naturally.
Press Cancel and remove the lid.
Using the sauté function, cook the peaches for about 15-20 minutes, stirring occasionally (this prevents the preserves from sticking/burning), until the peaches are broken down and the preserves have thickened up a bit. Break up any larger pieces, if desired. Alternatively, you can use an immersion blender to make a smoother jam, if preferred. I like chunky bits in mine.
Press Cancel and stir in the vanilla.
Transfer the hot jam to sterilized glass jars. Cover the hot preserves with sealing lids and secure with the corresponding canning rings. Turn the jars upside down for 15 minutes. Then turn the jars right-side up and allow the jam to continue cooling to room temperature.*
Store the sealed jam in a cool dry pantry for 3-6 months.* If the jars did not seal properly, store the jam in air-tight jars or containers in the refrigerator for up to 1 week or in the freezer for up to 3 months.**
Notes
* Proper Canning Seal: You’ll know the seal is successful if there is no give on the lid. If you can press down and feel the sealing lid give or move or hear it popping as you press down, the jar did not get a good seal and must be refrigerated or frozen.** (You can also can them in a water bath in the pressure cooker if you’re familiar with this process.)** To freeze the peach preserves in jars, ensure you leave at least one-half inch at the top of the jar to allow for expansion during the freezing process. Otherwise, your glass jar may break. When you’re ready to use your peach preserves, simply thaw the jar for 1-2 days in the refrigerator and use as you normally would.This recipe makes approximately 48 ounces of peach preserves or jam.
