In a saucepan over medium heat, add pears, spices, and sugars. Stir and bring to a boil.
Reduce heat to simmer, cover, and cook for 10 minutes. Uncover and use a fork, masher, or back of your spatula to crush the pears as much as you can.
Continue to cook for another 5-10 minutes until reduced and very slightly thickened, stirring occasionally. If the jam seems very thick, you can add 1 -2 tbsp of water to help it thin out a little to get to the consistency you like. If you add water though make sure to simmer for another minute for it to combine well.
Remove from heat, cool, and then pour into glass containers for storage.
