Add 2 cored and sliced pears and 1 cup of water to a medium pot.
Bring the ingredients to a boil and then stir until the pears have turned translucent.
Reduce the heat to a lower simmer and then add 1 cup of dark brown sugar.
Simmer together for about 30 minutes or until the brown sugar has dissolved.
Add in the zest from 1 lemon and stir.
Remove the mixture from the heat, let cool, and then strain into an airtight container.
