Delicious fried pumpkin cider doughnuts.
Bring the cider to a boil in a small saucepan and reduce to 1/2 cup. 3 to 4 minutes. Let cool.
In a small bowl, whisk together the confectioners' sugar, vinegar, vanilla, and 1 tablespoon water to make a thick glaze. You should be able to drizzle the glaze from a spoon. If its too thick add a little more water.
