Drain the pears and add to the boiling syrup. Boil for five minutes. Using a slotted spoon, divide pears between six jars. Remove the star anise and vanilla from the syrup, dividing them between jars. Ladle in hot syrup and peppercorns, leaving 1/2 inch of headspace. Run a plastic knife gently around the inside of jar to remove any air bubbles. Recheck the headspace. There may be extra syrup, but resist overfilling the jars.
05Wipe jar rims clean with a damp towel. Place the lids on the jars, screw on the rings and lower the jars back into the pot of boiling water. Return to a full boil and boil for 20 minutes. Transfer jars to a folded towel and let cool for 12 hours; you should hear them ping as they seal.06Once cool, test the seals by removing rings and lifting jars by the flat lids. If a lid releases, the seal has not formed. Unsealed jars should be refrigerated and used within a month, or reprocessed. Rings and jars may be reused, but a new flat lid must be used each time. To reprocess, reheat syrup to boiling, add back pears, return to boiling, then continue as before.
