2 blood oranges or regular oranges, sliced for garnish
4–6 (12 ounce) ginger beers
4 ounces London dry gin
1. To make the cranberry simple syrup: In a medium pot, bring 1/2 cup water, the honey, cranberries, rosemary, and cinnamon to a boil over high heat. Boil 3-5 minutes until the cranberries begin to burst, then remove from the heat. Let cool. Remove the rosemary and cardamon pods. Dump into a strainer to extract all of the syrup.
2. In a large pitcher, combine the cranberry syrup, rosé, elderflower liquor, cranberry juice, and gin. Chill until ready to serve, up to 2 days. (if using a sparkling rosé, add with ginger beers in step 3 just before serving)
3. Add the orange slices and ginger beer (and sparkling rosé, if using) just before serving.
