In a large pitcher, combine the clementine juice, lime juice, vodka and simply syrup. Stir well then refrigerate for at least 1 hour. Before serving, pour in the cold seltzer water, starting with 1 cup. Taste and if desired, add in more simple syrup and seltzer. Pour the mixture over crushed ice and garnish with mint, lime wedges and clementine segments!

[To make the simple syrup, combine equal parts sugar and water (like 1 cup each) in a saucepan over medium heat. Whisk until the sugar dissolves, bring it to a simmer, turn off the heat and cool the syrup to room temp. Store in the fridge.)
