In a saucepan add the sugars, wine, water, lemon zest, cinnamon stick, cranberries and cloves. Bring to a boil and reduce the liquid to 4 cups about 10 minutes.
2 cups cranberries, 2 cups red wine, 2 cups water, 1 cinnamon stick, 6 whole cloves, ⅔ cup brown sugar, ½ cup sugar, 1 tablespoon lemon zest
While the poaching liquid is reducing, using a sharp knife or potato peeler remove the skin of the pears as thinly as possible. Slice off a small amount of bottom of the pear just so it stands up when set in the Dutch oven.
In the Dutch oven add all of the pears and then pour the poaching liquid over the pears. The liquid may not cover the pears and that is ok.
Over medium-high heat bring the poaching liquid back to a boil, then reduce to a simmer, and cover. Cook for 30 minutes basting halfway through. A knife should pass through easily.
8 Bosc pears
Strain the poaching liquid. This can be reduced to a thicker sauce to become a glaze or can be served with the pear as is.
