Once the pears have reached a boil (I like a firm poached pear - so boil a bit longer if you like it softer) turn off the element.
Carefully remove the hot jars from the oven.
Place the pears in into the hot jars and fill to the top with syrup.
Place a seal on top and press it down while you screw the band on tightly.
Once the jars are cooled. Remove the bands and check the seals.
Wash the jars to remove any sticky syrup.
If the jar doesn’t seal I would recommend placing in a water bath to re-process it.
