In a large pot, combine the water, tea, and spices, bring to a gentle simmer for 10 minutes. Cover the pot, turn off the heat and let the chai steep for at least 30 minutes, or you can leave it overnight. The longer you leave the tea to steep, the stronger the flavor will be. Strain the liquid and discard the tea and spices. Add the sugar and bring to a simmer.
Peel and core the pears, and add them to the poaching liquid. Bring to a gentle simmer.
Slowly poach the pears, turning them on occasion to make sure all sides are equally cooked. This can take anywhere from 45 minutes to 2 hours, depending on how low the heat and how firm your pears.
To check for doneness, stick a skewer in the bottom of the pear, through the thickest part of the fruit. It should go into the flesh easily. If the pears are not the same size, you may need to take the smaller ones out before the larger ones.
Set them to drain and cool on a piece of parchment or wax paper. If you are not serving right away, cover the poached pears with plastic wrap and refrigerate for up to 2 days.
