Prepare a boiling water bath canner and 6 half pint jars. Wash 6 lids in warm, soapy water and set aside.
In a large, heavy-bottomed pot, combine chopped pears, sugar and vanilla beans (and all that bean-y goodness you scraped out). Cook over medium heat until the fruit can easily be smashed with the back of a wooden spoon. Use a potato masher or immersion blender to break the fruit down into a mostly-smooth sauce (remove the vanilla bean solids before blending).
Add the pectin and bring to a rolling boil. Let boil for a full five minutes in order to active the pectin, so that the finished product will have a nice jammy consistency.
Funnel finished jam in the prepared jars, leaving 1/2 inch headspace. Wipe rims, apply lids and rings and process in a boiling water bath canning for 10 minutes (if you live above 1,000 feet in elevation, adjust your processing time accordingly).
When the processing time is finished, turn off the heat under the pot and remove the lid. Let the jars rest in the cooling water for 5 minutes. When that time is up, remove the jars from pot and place them on a wooden board or towel-lined countertop.
Let the jars rest undisturbed for at least 12 hours and then check the seals. Sealed jars are shelf stable for up to 18 months. Any unsealed jars should be refrigerated and used promptly.
