Pit the peaches and dice them up. Toss them into the pressure cooker insert.
Toss in the rest of the ingredients over the diced peaches. Start the pressure cooker in manual mode for 1 minute at high pressure.
When it is done cooking, release the pressure naturally. Move the Instant Pot to the saute function and simmer for 12 to 15 minutes.
Grab your potato masher, mash the peaches into a puree. Store your peach jam in a mason jar. It will last for a few weeks.
