I combine equal parts sugar and water in a small saucepan and warm it over medium heat. I stir gently until the sugar fully dissolves, which only takes about three minutes. Then I pull it off the heat and let it cool completely before using it in the drink.
In my large pitcher, I pour in the cranberry juice, fresh orange juice, vodka, and orange liqueur. I give everything a good stir so the flavors start blending right away. This base can sit in the fridge for hours if I'm getting ahead on prep.
Once my syrup has cooled, I pour it straight into the pitcher with the other ingredients. I stir again to make sure the sweetness is evenly distributed through the whole batch. I always taste it here and adjust if I want it sweeter or more tart.
I pop the pitcher in the fridge for at least 30 minutes before serving. Chilling it properly matters more than people think, since a cold base means less ice melting in the glass later. If I'm short on time, I add extra ice directly to the pitcher instead.
Right before guests arrive, I fill glasses with ice and pour the chilled base over the top. I finish each glass with a splash of club soda or ginger beer for that fresh bubbly lift. A quick stir, a garnish, and it's ready to hand off.
