Serve this refreshing cocktail at your holiday get-together.
In a large pitcher, whisk together vodka, limoncello liqueur, fresh orange juice, and fresh lemon juice. To serve, divide among 8 ice-filled glasses and top with seltzer. Garnish with lemon zest.
If you don't have limoncello, an Italian lemon liqueur, you can make a similar tasting drink -- increase the vodka to 1 1/2 cups and add 3/4 cup Lemon Syrup.
