2 oranges
16 ounces vodka, chilled
5 cups orange juice, chilled
2 cup crushed ice for serving
Wash oranges and slice into 1/4-inch rounds. In a large bowl, using a wooden spoon, muddle the orange slices, releasing the oil in the peel and the pulp from the rounds. Add the vodka, and mix. Then add the orange juice, and mix well.
Add crushed ice to 8 glasses. Pour in drink mixture, including orange rounds in each serving.
