Wash, peel, core, and dice pears into half inch cubes.
Place diced pears into large bowl with sugar and both halves of lemons squeezed.
Stir to combine everything. Make sure pears are coated in sugar and lemon juice.
Cover tightly with plastic wrap and leave overnight in fridge. Pears will release a lot of juice.
The next day, pour pears with the juice that has formed in the bottom of the bowl, the lemon halves and the peeled cut in half into a tall sided pot.
Bring the mixture up to a boil over medium high heat. Be careful to stir and not let it bubble out of the pot.
Cook the pears for 2 hours or until the pear juice has turned into a thick syrup and the pears are translucent and soft. Be sure to stir the pears often when the mixture starts to thicken.
Discard the ginger and lemons.
Place hot pear preserves into clean mason jars. I filled 6, four-ounce mason jars with this recipe.
Seal the jars with lids. You can heat treat them in a stock pot of boiling water for 10 minutes.
Allow the jars to cool overnight undisturbed.
Sealed pear jars will last up to a year. Unsealed jars will last up to 2 months in the refrigerator.
Enjoy!
