Turn on the broiler and drain the pears, saving the poaching liquid, and returning it to the saucepan. Gently place the poached pear slices on a baking sheet covered with foil. Sprinkle the pears with a thin coating of granulated sugar and place them under the broiler just until they begin to brown or char a tiny bit along the edges, about 2 minutes. (Every broiler is different, so check them every 30 seconds or so!) Alternately, you can use a kitchen blow torch
to brown the sugar.
